If you are diabetic, please don’t buy this watch. It is very dangerous if you use the readings to take insulin. This watch keeps giving a blood sugar reading between 77-94 mg/dL when the accurate reading on the Contour next ONE meter is 278 mg/dl, 283 on the contour next EZ and is 293 mg/dl on the True Matrix Air. I had over 75 readings in 3 days and reset this device to factory settings twice. It is NOT EVEN 5% ACCURATE. I was hoping to have some accuracy near the 70-80% to use it as a guide not a measure but it is not. The blood pressure accuracy is near the 60-70% mark compared with 4 blood pressure meters. I didn’t try it as a sports watch as it may serve the purpose. It is a very nice watch, nice screen, very responsive and comfortable to wear. I wish it does what it says it does, it would have been a must to have but it is not. It is a marketing gimmick prying on your health.
Is there any kind of synchronization between your actual glucose level and the watch's reading, similar to how the blood pressure is synchronized? Thanks.
@@woofwoof416 simply not possible to measure anything without invasive sensors that have to be inserted into body, aka CGMs. This "watch" simply lies and throws up a number to make you feel comfortable.
The reason for such huge difference is 1. The reading it shows is Haha1C is Glycocelated Harmoglobin A1c ie weighted average of 3 month blood sugar level in your blood. Now from this , v can average out it like 26 points for each level. So if 5.74 is reading then 5.74 X 26 is nearly average daily blood sugar of 135 approx from this But this is not a true reflection of your daily sugar On one particular day u may increase your blood sugar to 250 but still this is going to 5.74 only since it calculates average for 3 months n not on that day To check accuracy of Hba1C in this watch, u have to compare it with a Lab readings of Hba1C of your blood n check
Hey Dave, thanks for the review. I apreciate your speed of delivery. I hate those fast talking content creators on RUclips. You talk like a normal human being. Please remember that a lot of people around the worls, whose native tongue is not English plus a lot of viewers who are of the 'elderly' generation are also watching your videos. Your talking speed is just right for those folks.
This video is more like a product overview and less of a review. A review has pros\cons that informs people of the good and bad. What I find missing is some type of validation or comparison to data that is known to be accurate. Such as walking 1000 steps, measure blood pressure with a real blood pressure device, checking glucose levels using a Libre monitor, etc. I have checked out a couple of these cheap all-in-one health watches from china and the ones I have tested have not been accurate or border on faking data completely. In the video there are repeated comments of "Seems reasonable to me" which does not provide any information for how data compares to accurate data. Even comparing it to Fitbit data or Apple watch data would be better than just commenting, "Seems reasonable".
The pace of your commentary is perfect for me. Please don't change. I am understanding every word. Sometimes I can't understand some American accents - especially when it's too fast! 🇬🇧
I have separate sensors for each of these functions, with the exception of EKG. If 2 or 3 of these measurements work within %80 accuracy, its well worth it. The problem with this video is he does not measure any of the parameters against another meter. I will do that, and post back.
Got the watch, here are my figures: 8:23am cgm=148 watch=99.6 bp=139/87 watch=119/80 hr=65 watch=64 ox=93% watch=97% 10am cgm=193 watch=148 bp=128/76 watch=120/84 hr=84 watch=78 ox=94 watch=97% 2:10 cgm140 watch=151 bp=121/72 watch=114/76 hr=85 watch=86 ox=95% watch=96% 5:30 cgm 110 watch=85 bp=133/81 watch=115/86 hr=72 watch=75 ox=95% watch=99% Units are mg/dl, mmhg, bpm, %spo2 The meters used for compare were: Freestyle libre2, Omron hem-712c Walgreens oxywatch. As expected, the cgm and blood pressure readings vary quite a bit. I was mainly looking to see they trend in the correct direction, and they appeared to. When my CGM hit a low of 94, so did the watch, meaning it would be a reasonable alert of low blood sugar, which is the important fact. Heart rate and blood oxygen have firm science behind them for reading via light through the skin. Blood sugar and pressure is problematic. A lot of companies have thrown money at the problem, and I don't have any idea how the blood pressure is supposed to work. So take it with a grain of salt. What I mainly got out of this is that if we don't have a watch that can "watch" your important body statistics, we are on the edge of it. For a 65 year old like me, that's facinating. For you kids, perhaps not. Finally, the hookup to an Android phone didn't work. At all. The app saw the watch, and displayed it as an E600, then failed to connect to it. It told me to turn the bluetooth on and off, and I tried this in various combinations until I was turning blue. It obviously can see it, it appears to be crappy software to me. tried with a Samsung A71 phone with the latest Android version.
Thanks for your input. When I setup my hearing aids I had to turn off the wifi until setup was complete. I also have an Android. Can the glucose readings be set for mg/dl?
I bought something very similar, not expecting any real accuracy. As I have found with the three smart watches I have bought, blood pressure reading is totally inaccurate when compared to a proper machine. Pulse seems okay and as far as I know the blood oxygen is also okay. The glucose reading is dangerously inaccurate when compared to finger prick tests, I have seen a finger prick test as high as 11 mmol/l and the watch was saying 5. something. I have uploaded a comparison video comparing the watch to my Contour Next One. I am not convinced of the accuracy of the graph either, if you compare different days the peaks always seem to happen at the same time of day, even when you eat at different times, although I still haven't made my mind up about that, must try skipping a meal to see if that shows up, but food is nice! I have just changed my eating pattern so maybe the pretty pictures will change after all!
I am a diabetic, my blood glucose will increase when I am fasting. I can go to bed with a perfect glucose level and wake up to an extremely elevated glucose level. Glucose is the body's fuel. Our liver stores glucose to help us when our glucose levels get low. My liver will open the floodgates, dumping way too much glucose into my system to compensate for not eating. I need to eat a small amount of protein before going to bed & a small amount of carbs & protein upon waking, this way I can control my morning Bgl nicely.This is a phenomenon which happens with some diabetics, but not all diabetics.
It is common that blood sugar rises in the AM. This is called the "dawn effect". It is a biological adaptation that was to put extra carbs in your system when you get up so you are ready to run after or away from something (most of the existence of man we were either hunter or hunted, not like now).
My experiences with this watch: 1. pedometer is insensitive, records about 60-80% of the steps. I take 100 steps and it shows between 60 and 80 2. The battery holds for 3 days. Or less. 3. The blood glucose measurement gives me sometimes the feeling that it is 'fake'. The waves look the same everyday, independently when and what I eat, how much I exercise. 4. The Amoled display is readable in full sunshine. 5. The software is somewhat buggy.
A partial thromboplastin time (PTT) test uses a blood sample to measure how long it takes for your blood to make a clot. Normally, when you get a cut or injury that causes bleeding, many different types of proteins in your blood work together to make a clot to stop the bleeding.
Based on your video I bought the E600. It works exactly as you reported and I am very happy with the results. Infact measuring my blood pressure is more consistent on this watch than my very expensive BP monitor. Blood Glucose results seem reasonable and move according teasting after eating and after 2 hours. Thanks for saving me hours of research and frustration.
There is a German guy ( I think) somewhere on you tube who tested three of these and came to the conclusion that they were useless. He figures they don’t work. They might show a reading that seems okay until you take a sugar hit and the watch misses it. Thats not much use! I wouldn’’t waste my money on them.
Pulse transit time (PTT) is the time elapsed for the pressure wave to travel between two arterial sites. According to the well-known Moens-Kortweg equation, PTT decreases as the arteries stiffen. Since arterial stiffness increases with blood pressure (BP) via the mechanical properties of the arterial wall, PTT often shows a tight, inverse relationship with BP in individual subjects. Moreover, PTT can be measured simply as the relative timing between proximal and distal waveforms indicative of arterial pulsations. For these reasons, PTT is being widely investigated at present to achieve convenient, cuff-less BP monitoring (see recent reviews1,2,3).
“Measurement seems reasonable…” it’s so easy to test this against other known reliable ways of measurement, until you do that, your review is worthless
Glucose device is on it's way. I never meant for this review to attain the attention it has. Do not trust any of these smartwatches for blood glucose. The technology is not there yet. ruclips.net/video/zfG4wl_R6Zo/видео.html
A cup of coffee will raise the blood sugar by stimulating sympathetic system, if you drink lot of coffee you become jittery due to over stimulation of Sympathetic system which basically mean increase in adrenalin which in turn increase the glucose out put.
I have this and the EP01. They are pretty much the same. The glucose function on mine works better than expected. The sleep function on the E600 has been a let down compared to the EP01. Both have great ECG functions. There is an addon ECG strap and hand held that make it more accurate. The heart rate function also works great even with tachycardia. I also never got the PTT to work. Watch may need an update for that to function.
Blood glucose testing is needed to be 💯% accurate due to both Hyper & Hypos. I use freestyle libre sensors and app in my phone, and its 💯% and my diabetic specialist can via my stuff via linking to app
PTT , my guess, Pulse transit time (PTT) is a measurement of the time it takes for an arterial pulse wave to reach the periphery. PTT can be calculated from the finger photoplethysmograph (PPG) of the oxygen saturation monitor and the R-wave of the electrocardiogram (ECG) during a polysomnogram.
I checked the blood glucose function for a couple of days in combination with a Dexcom G6 continuous glucose sensor. The non invasive E600 values are completely random and totally useless. So definitely not ready yet and no chance to get an FDA approval.
Partial thromboplastin time (PTT) is the time it takes for a patient's blood to form a clot as measured in seconds. It is used to measure the activity of the intrinsic pathway of the clotting cascade.
Did you test any of the watch readings against real monitor equipment? thanks for your opinion but that doesn’t help us much if the data the watch gives is not accurate
In order to verify the accuracy of the BG measurement you would have to take a couple of measurements within a couple of minutes to see if there is a large variance (there should not be) and also test it with a finger prick blood tester to see if the result is the same or close to it. If your regular BG equipment shows you 1 value and the watch is way off that value, then you can consider it completely unreliable in monitoring your BG at any time.
I have an alternative method. We could look at the chart of blood glucose over the course of the day - it's shown in the video!... Then we could look at the same chart for other people and see if its any different. My own chart (albeit on a different smart watch) is almost identical every day... AND it's almost identical to the one shown in this video... AND its almost identical to one shown on a review of my watch. For me to even start considering that this could be giving meaningful data, I would need to see a materially different chart of blood glucose over the course of a day. Could be for a different person. Could be for a different person for different days. As far as I can see, it doesn't make any noticeable difference who wears the watch or what they eat or do. Hope I'm wrong. Would love to see some different datasets.
@@user-yj4wo2co7u I have another way. I have been using it for 11 days now and I have been taking my BG measurement with my medical BG meter and comparing it to the watch's BG meter twice a day. Here's the result. The watch gives you a value between 6.01 and 6.99 and never above or below those values. How do I knot this? because I deliberately bottomed out my BG to the 3 range on 1 occasion and spiked it to the 9 range on another and when you're in the 3 range, you can feel it (You feel nauseous and sick) and the BG meter on the watch gave me 6.48 and when I was in the 9 range, it gave me a reading of 6.20. My assessment is that it's a random # generator between 6.01 and 6.99 and nothing more. DO NOT RELY on this watch's BG function (Or any of the others) to give an accurate reading because I also find that the Blood pressure reading is also off and on several occasions, it didn't register sleep at any time during the night. It's a flashy toy, nothing more.
You did not compare ANY of these health "measurements" this devices spews out against a device with known accuracy. Even something as simple as a blood pressure calf. This is a demonstration and NOT a "review"! A waist of time!!! 👎👎👎👎
I have an E600 and I can tell you the PTT test is for when you are wearing the chest strap and do a full ECG. Without the chest strap/monitor it does not work. That is why you were not able to figure out what it did.
After a month or so having this band, I cant recommend it based on my experience. Biggest issue for me is the battery life, its abysmal, it lasts maybe 4 days, its not enough and I find myself with a dead watch at the most inconvenient of times, and with a custom charger cable, unable to charge it. Second - it locks up so that it doesn't wake up when touching the screen. The only way to revive it is to plug it to the charger, which again is inconvenient. Third, it fails to monitor mid-sleep, it has happened multiple times that it stops monitoring in the middle of the night. It also doesnt detect when I take naps. I had watches in the past that would detect nap time and report it. this one, starts at midnight and thats it for blood oxygen. Blood glucose is imo fake. the chart is the same day after day which I think is impossible. Overall this is probably the worst watch I've had so far and I have had a few already. Needless to say I am looking for another watch with the same features that actually works as intended and I am open for Sugestions (dont sugest the e500 and e400, they are the same thing except for the watch form).
I have this E600 too, but the Blood Glucose level seemed to be cheating, it made no differences whether I eat anything at all, at around 1200 noon, it still gives the same blood glucose variation everyday!!! Hope you would let me know if I did something wrong!!!
It seems to not at all be accurate for many people. I don't trust the technology yet, but even then skin color, skin hydration, ambient/stray light and other factors would come into play. This should not be used as a medical device.
I wish you would have tested Glucose monitoring alongside the finger prick to see how accurate it is. Don't want to buy if it's giving me a false sense of security.
I found the private blood glucose setting and will take my fasting BGL tomorrow morning. I will do a full day of 7 readings on my bel meter and my E600 watch to compare them. I also wondered how the skin colour option on the initial H BAND app setup affects the bgl reading but cannot find how to adjust after installation - may have to deinstall get back to this.
Bear I bought the E600 Smart Watch. I have tested my glucose readings against my Glucose Meter and found its readings have been in the ballpark. A little lower by .53. My Blood pressure is about as accurate as my Atoma blood pressure sleeve. It is more consistent. For the price, I got what I was expecting.
I’ve been anxiously waiting for Apple to come up with a glucose monitoring mechanism for their watch, so it just too obvious to me that this is a scam.
I don't know how accurate these watches are with Blood glucose since the one I bought will still give a glucose reading even while the watch is off the wrist sitting on the coffee table! Other reflective sensors like a pulse oximeter will not work if they aren't attached to a body part.
I think the test that does not seem to work you have to put your arm close to your heart. I know the cuff blood pressure monitor I need to do that before it will work. It would have been nice to test this with a blood glucose meter to see how accurate the readings were.
I am not used to the numbers of bg monitoring, does it have the more traditional usa numbers like Ideal is 100 and low is below 80 and high is above 120.
Waking up with high blood sugar is normal. It even has a name the 'Dawn Phenomenon'. The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. Fitness gaming is for more interactive games that make you move. Partial thromboplastin time (PTT) is the time it takes for a patient's blood to form a clot as measured in seconds. PTT result may also be due to: Bleeding disorders , a group of conditions in which there is a problem with the body's blood clotting process. Disorder in which the proteins that control blood clotting become over active ( disseminated intravascular coagulation ).
Nobody has really explained this to my satisfaction yet. It is an optical sensor that detects light reflected back to the watch after it transmits light into the body, then some voodoo algorithm does some sort of signal processing to generate a number. Some sort of optical absorption spectroscopy. Until somebody explains it to me in a way that makes sense I don't trust it. I understand spectroscopy, but I'm not sure I believe $30 Chinese smartwatches are doing it the right way.
Measured in seconds to clot formation, normal PTT can vary based on laboratory or institution; however, normal PTT is between 25 to 35. PTT ranges are used to classify heparin dosing schemes as low or high intensity and to ensure effective dosing.
I understand totally. BUT you can get some good deals from there for exactly the same watch you'd pay 2x or 3x more in other places. I'm on a really tight budget on this channel so I usually scout out the watch I want to review next and then see if I can find it on AliExpress for less since I know I'm essentially buying it just to do the review and then give it away. I've got the Rogbid Rowatch 4 coming next and then a new surprise on deck after that. Both have blood glucose and the latter has brand new features that I've *never* seen in a smartwatch, so that one will be totally unique. Hopefully the Rowatch 4 review will come out this weekend and I'll have a coupon code for my viewers to save you some money. Thanks for at least partially watching! ;-)
have you considered pricking your finger and testing blood glucose for real to see how this watch compares? not the most pleasant of things to do, but that's how you would test its accuracy ...
I've thought about it, but I don't need to test my blood normally and don't have a kit to do so, so I'm not inclined to go out and buy a testing kit to compare to devices that actually claim not to be medical devices. I don't want to send the wrong message or make any medical claims. I hope everyone understands.
He didn't test it because he knew it is bullsh.t It is just a toy. And to get a regular testkit is free and you get 5 or 10 Teststrips included. Those company's generate there revenue by selling the Teststrips afterwards. So it was laziness or he knew it will never be similar. If you have a look 3:25 the glucose level has 2 similar spikes into 4hours. This is impossible because it never falls like it rises and not in that short time
What is it used for? A PTT test is used to check for problems with a specific group of blood clotting factors. The test is done to: Find the cause of too much bruising or bleeding. Find the cause of clotting problems. Causes can include certain autoimmune diseases such as lupus and antiphospholipid syndrome (APS). Monitor people taking heparin, a type of medicine that's used to prevent and treat blood clots. PTT testing can help make sure the dose is safe and effective. Check the risk for possible bleeding problems before surgery or medical procedures. (A PTT test is not always used as a routine test before surgery. It may be used for certain people who may have a risk for bleeding problems).
I would like to reach out this company and see if we can partner to test feasibility and accuracy of using this smart watch as part of doctoral training. Are you able to provide contacts?
No, I have no idea who makes it, but I think there are only a handful or fewer companies in China who make all these low-end devices and then they get branded under different names.
I bought one of these blood glucose watches from another company. I will check it and hope it helps. I saw a video from someone who took blood from both sides of the same finger and got a 30 point difference on a glocose meter so even them are not 100% accurate.
I guess even real glucose monitors have a significant % deviation in them. That said, I have since come to believe the non-invasive smartwatches are not even close. They show peaks of similar magnitude near normal meal times, but do not deviate if you skip a meal or just have coffee or water vs. a full meal. They are not medical devices and should not be treated as such.
The blood glocose measures in MMOL, does the watch allow change to mg, which is what we use in the US. I know the F100 smart watch uses a different app, and that app has a feature to change the measuring protocol in its settings from MMOL to mg.
5.7 mmol shown in video is about 102 mg so he is good ! BUT, why didn't he do a simultaneous fingerprick test with a standard glucose meter ? He already knows that MOST everyone wants to see that ? right ? Please do it and repost another video . Thanks ! Also, does it do continuous monitoring and save the results ( I don't think so ).
PTT is likely the speed of the pulse wave. Since it is able to measure ECG and the blood pressure \ pulse by local sensors, I would expect that you also have to press the lateral sensors for that. If the speed is too high it would mean that the central arteries are too stiff, indicating a higher risk for CVD. Thank you very much for that review, it helps me a lot. I have sth else to mention. Of course my observations are naturally very limited, yet... First, your heart rate is quite high. second, you talk fast, third, your fingers tremble if you don't focus on them, fourth, there seem to be issues with your sleep. This points to an overactivation of the sympatikus branch of the vegetative nervous system, OR a specific condition regarding the alpha-2 adrenerg receptors. It can be treated by very (!) small doses of beta blockers ...I suggest you should talk to a specialized doctor
Hmm, let the smart dummy speed up replay. Speed OK. I hate when I get Alibaba video where they high speed videos like they do not have MB capacity. Here I woulda preferred seeing the back of watch and a description of what YOU think are the sensors. Or if you coulda found out from manufacturer? Google says PTT is clotting factor, you coulda show a measurement?? Unless it was not working? and did not give a reading?
Obviously a every based review! There's no way to reliability measure BP and BS photometrically on the wrist. Also the ECG coming out with the QRST peaks as shown looks like a too good to be true scam. ECG potentials are in the single digit mV range measured on the thorax with wet electrodes. Impossible to reproduce with fingers touching for several reasons. I think they just use the pulse from the photometry and draw stored ECG sequence which they superimpose with the galvanic potential of the fingers touching. I have developed ECG instruments to know that in this arrangement it can't work. In other words sorry to say but this must be a scam!
Yes. You have to buy the accessory version with the chest strap. According to good ole chatgpt: Pulse transit time is a measure of the time it takes for the arterial pulse wave to travel between two points in the body, typically from the heart to a peripheral site such as the wrist or finger. This measurement can be used to estimate cardiovascular function and has been studied as a potential marker for various health conditions. Some chest strap heart rate monitors include sensors that can also measure PTT in addition to heart rate, providing additional data for fitness and health tracking
Fitness gaming. You ever hear of the Wii? VR? They work great to get those sedentary introverts up out of their chairs all day, and actually moving. Is it better than actually exercising? No. But its better than nothing, right? And umm, some of those fitness games can actually make you sweat after awhile. ;)
I believe my body of work on my Fitness Tracker & Smartwatch Review Playlist paints a different picture as does this video: ruclips.net/video/zfG4wl_R6Zo/видео.html
I love the E300, but it does not do blood glucose. For that I prefer the E600. E600 does not do laser therapy, so if you believe in that then the E300 gets the nod.
Can you comment on the number of watch faces available from the app? Also I'm interested in the apnea detection, did you actually have the watch vibrate? And what is your observation of the battery life with all the sensors on?
6 dial faces are stored on the watch and the app seems to have 50 more, plus you can use a custom photo as a watch face. I had all the auto-measurements turned on but did not have an apnea event while testing, so I cannot verify that particular alarm. I easily got 5 days on one charge with the screen on the lowest brightness, screen time set to 5 seconds and lift-your-wrist feature turned off. Plus I only connected to BLE to synch data.
@@hammerjoe2008 No bro it's not I checked through other reviewers it doesn't provide accurate data as compared to other watches, pls ignore him and thx.
Is the spo2 reading accurate ? How did you test it ? Holding breath to see if it drops ? I dont mean accurate to the % but accurate enough to show it dropping and rising.
I also found the blood glucose readings to be absolutely wrong all of the time. Similarly with the blood oxygen measurement - the best I csan get is 95 (average probably 93), but the watch always puts me at 98-99.
@@DaveTheKayaker oh wow. Yeah it works on my e400. Once your on the APP, go to the ECG part and then do it. It should work like that. If not that sucks.

Finally, the hookup to an Android phone didn't work. At all. The app saw the watch, and displayed it as an E600, then failed to connect to it. It told me to turn the bluetooth on and off, and I tried this in various combinations until I was turning blue. It obviously can see it, it appears to be crappy software to me. tried with a Samsung A71 phone with the latest Android version.
Thanks for your input. When I setup my hearing aids I had to turn off the wifi until setup was complete. I also have an Android. Can the glucose readings be set for mg/dl?
Liver makes glucose in the morning. If you see glucose spike in the morning mean that you have insulin resistance.
I bought something very similar, not expecting any real accuracy. As I have found with the three smart watches I have bought, blood pressure reading is totally inaccurate when compared to a proper machine. Pulse seems okay and as far as I know the blood oxygen is also okay. The glucose reading is dangerously inaccurate when compared to finger prick tests, I have seen a finger prick test as high as 11 mmol/l and the watch was saying 5. something. I have uploaded a comparison video comparing the watch to my Contour Next One. I am not convinced of the accuracy of the graph either, if you compare different days the peaks always seem to happen at the same time of day, even when you eat at different times, although I still haven't made my mind up about that, must try skipping a meal to see if that shows up, but food is nice! I have just changed my eating pattern so maybe the pretty pictures will change after all!
Thank you for the review!Your talking speed is just fine.
Thanks for watching!
I am a diabetic, my blood glucose will increase when I am fasting. I can go to bed with a perfect glucose level and wake up to an extremely elevated glucose level. Glucose is the body's fuel. Our liver stores glucose to help us when our glucose levels get low. My liver will open the floodgates, dumping way too much glucose into my system to compensate for not eating. I need to eat a small amount of protein before going to bed & a small amount of carbs & protein upon waking, this way I can control my morning Bgl nicely.This is a phenomenon which happens with some diabetics, but not all diabetics.
Karenhale, I take the supplement Berberine, and it alleviates those morning highs.
It is common that blood sugar rises in the AM. This is called the "dawn effect". It is a biological adaptation that was to put extra carbs in your system when you get up so you are ready to run after or away from something (most of the existence of man we were either hunter or hunted, not like now).
Glucose rise on waking is called the dawn effect, my sugar drops at night and in the morning it is high generally
I think the speed your speech is is just right. Some people just have to have something to complain about.
My experiences with this watch:
1. pedometer is insensitive, records about 60-80% of the steps. I take 100 steps and it shows between 60 and 80
2. The battery holds for 3 days. Or less.
3. The blood glucose measurement gives me sometimes the feeling that it is 'fake'. The waves look the same everyday, independently when and what I eat, how much I exercise.
4. The Amoled display is readable in full sunshine.
5. The software is somewhat buggy.
A partial thromboplastin time (PTT) test uses a blood sample to measure how long it takes for your blood to make a clot. Normally, when you get a cut or injury that causes bleeding, many different types of proteins in your blood work together to make a clot to stop the bleeding.
Based on your video I bought the E600. It works exactly as you reported and I am very happy with the results. Infact measuring my blood pressure is more consistent on this watch than my very expensive BP monitor. Blood Glucose results seem reasonable and move according teasting after eating and after 2 hours. Thanks for saving me hours of research and frustration.
Hi Norm, how accurate are the Blood glucose results?
Can the glucose readings be changed to mg/dl?
The morning rise of glucose with out first eating is normal. It’s often called the “dawn phenomenon “ or “dawn effect”.
There is a German guy ( I think) somewhere on you tube who tested three of these and came to the conclusion that they were useless. He figures they don’t work. They might show a reading that seems okay until you take a sugar hit and the watch misses it. Thats not much use! I wouldn’’t waste my money on them.
Pulse transit time (PTT) is the time elapsed for the pressure wave to travel between two arterial sites. According to the well-known Moens-Kortweg equation, PTT decreases as the arteries stiffen. Since arterial stiffness increases with blood pressure (BP) via the mechanical properties of the arterial wall, PTT often shows a tight, inverse relationship with BP in individual subjects. Moreover, PTT can be measured simply as the relative timing between proximal and distal waveforms indicative of arterial pulsations. For these reasons, PTT is being widely investigated at present to achieve convenient, cuff-less BP monitoring (see recent reviews1,2,3).
“Measurement seems reasonable…” it’s so easy to test this against other known reliable ways of measurement, until you do that, your review is worthless
Glucose device is on it's way. I never meant for this review to attain the attention it has. Do not trust any of these smartwatches for blood glucose. The technology is not there yet. ruclips.net/video/zfG4wl_R6Zo/видео.html
A cup of coffee will raise the blood sugar by stimulating sympathetic system, if you drink lot of coffee you become jittery due to over stimulation of Sympathetic system which basically mean increase in adrenalin which in turn increase the glucose out put.
Thanks for explaining the mechanism. I was wondering how it is my drinking coffee in the morning raises my blood sugar. :)
I have this and the EP01. They are pretty much the same. The glucose function on mine works better than expected. The sleep function on the E600 has been a let down compared to the EP01. Both have great ECG functions. There is an addon ECG strap and hand held that make it more accurate. The heart rate function also works great even with tachycardia. I also never got the PTT to work. Watch may need an update for that to function.
Is the glucose monitor accurate
The obvious thing to do is to test your blood sugar with a test strip and then compare the results with the watch, isn't it?
His lack of this makes the review worthless
Not accurate.
Blood glucose testing is needed to be 💯% accurate due to both Hyper & Hypos. I use freestyle libre sensors and app in my phone, and its 💯% and my diabetic specialist can via my stuff via linking to app
PTT , my guess, Pulse transit time (PTT) is a measurement of the time it takes for an arterial pulse wave to reach the periphery. PTT can be calculated from the finger photoplethysmograph (PPG) of the oxygen saturation monitor and the R-wave of the electrocardiogram (ECG) during a polysomnogram.
@MacChew, yes, the PTT function must be enabled to measure the ECG, and I believe an additional part (belt) is required.
I checked the blood glucose function for a couple of days in combination with a Dexcom G6 continuous glucose sensor. The non invasive E600 values are completely random and totally useless. So definitely not ready yet and no chance to get an FDA approval.
But buy it you force a technical progress forward
How do you know it’s accurate? You’re not measuring against a BG meter like acu chek or similar.
You don't talk slow, those weirdos have issues
Partial thromboplastin time (PTT) is the time it takes for a patient's blood to form a clot as measured in seconds. It is used to measure the activity of the intrinsic pathway of the clotting cascade.
It turns out to be Pulse Transit Time.
Did you test any of the watch readings against real monitor equipment? thanks for your opinion but that doesn’t help us much if the data the watch gives is not accurate
Thank you for this helpful review. I find your speaking speed just fine. ❤
Thank you. Others complain I'm too fast and sound like I'm on meth, lol.
@@DaveTheKayaker Me thinks it is not you that may be on meth, lol!
Blood sugar is usually high first thing in the morning even after a pretty long fast, so your findings are that unusual.
In order to verify the accuracy of the BG measurement you would have to take a couple of measurements within a couple of minutes to see if there is a large variance (there should not be) and also test it with a finger prick blood tester to see if the result is the same or close to it. If your regular BG equipment shows you 1 value and the watch is way off that value, then you can consider it completely unreliable in monitoring your BG at any time.
I have an alternative method. We could look at the chart of blood glucose over the course of the day - it's shown in the video!... Then we could look at the same chart for other people and see if its any different. My own chart (albeit on a different smart watch) is almost identical every day... AND it's almost identical to the one shown in this video... AND its almost identical to one shown on a review of my watch. For me to even start considering that this could be giving meaningful data, I would need to see a materially different chart of blood glucose over the course of a day. Could be for a different person. Could be for a different person for different days. As far as I can see, it doesn't make any noticeable difference who wears the watch or what they eat or do. Hope I'm wrong. Would love to see some different datasets.
@@user-yj4wo2co7u I have another way. I have been using it for 11 days now and I have been taking my BG measurement with my medical BG meter and comparing it to the watch's BG meter twice a day.
Here's the result. The watch gives you a value between 6.01 and 6.99 and never above or below those values. How do I knot this? because I deliberately bottomed out my BG to the 3 range on 1 occasion and spiked it to the 9 range on another and when you're in the 3 range, you can feel it (You feel nauseous and sick) and the BG meter on the watch gave me 6.48 and when I was in the 9 range, it gave me a reading of 6.20.
My assessment is that it's a random # generator between 6.01 and 6.99 and nothing more.
DO NOT RELY on this watch's BG function (Or any of the others) to give an accurate reading because I also find that the Blood pressure reading is also off and on several occasions, it didn't register sleep at any time during the night.
It's a flashy toy, nothing more.
You did not compare ANY of these health "measurements" this devices spews out against a device with known accuracy. Even something as simple as a blood pressure calf. This is a demonstration and NOT a "review"! A waist of time!!!
👎👎👎👎
ruclips.net/video/zfG4wl_R6Zo/видео.html
I have an E600 and I can tell you the PTT test is for when you are wearing the chest strap and do a full ECG. Without the chest strap/monitor it does not work. That is why you were not able to figure out what it did.
Thanks. I'm testing this now with the e610 with the chest strap.
After a month or so having this band, I cant recommend it based on my experience.
Biggest issue for me is the battery life, its abysmal, it lasts maybe 4 days, its not enough and I find myself with a dead watch at the most inconvenient of times, and with a custom charger cable, unable to charge it.
Second - it locks up so that it doesn't wake up when touching the screen. The only way to revive it is to plug it to the charger, which again is inconvenient.
Third, it fails to monitor mid-sleep, it has happened multiple times that it stops monitoring in the middle of the night. It also doesnt detect when I take naps. I had watches in the past that would detect nap time and report it. this one, starts at midnight and thats it for blood oxygen.
Blood glucose is imo fake. the chart is the same day after day which I think is impossible.
Overall this is probably the worst watch I've had so far and I have had a few already. Needless to say I am looking for another watch with the same features that actually works as intended and I am open for Sugestions (dont sugest the e500 and e400, they are the same thing except for the watch form).
I have this E600 too, but the Blood Glucose level seemed to be cheating, it made no differences whether I eat anything at all, at around 1200 noon, it still gives the same blood glucose variation everyday!!!
Hope you would let me know if I did something wrong!!!
It seems to not at all be accurate for many people. I don't trust the technology yet, but even then skin color, skin hydration, ambient/stray light and other factors would come into play. This should not be used as a medical device.
@@DaveTheKayaker I discovered with mine that it produces exactly the same waveform day after day. I dont think thats normal.
@@hammerjoe2008 It might be if you are not diabetic.
I wish you would have tested Glucose monitoring alongside the finger prick to see how accurate it is. Don't want to buy if it's giving me a false sense of security.
Don't trust any of these watches to be accurate for blood glucose.
I agree with all of it. I like the fact that he has given a review, yet without comparing it to actual monitors the reviews become worthless.
I found the private blood glucose setting and will take my fasting BGL tomorrow morning. I will do a full day of 7 readings on my bel meter and my E600 watch to compare them. I also wondered how the skin colour option on the initial H BAND app setup affects the bgl reading but cannot find how to adjust after installation - may have to deinstall get back to this.
Does the watch have the mg/dL unit of measurement? That's the only one I'm interested in. Please lemme know.

I bought the E600 Smart Watch. I have tested my glucose readings against my Glucose Meter and found its readings have been in the ballpark. A little lower by .53. My Blood pressure is about as accurate as my Atoma blood pressure sleeve. It is more consistent. For the price, I got what I was expecting.
Hey, take your time, I like how you take your time.
When you wake, cortisol rises which causes blood sugar to rise. Normal response.
Caffeine from coffee will also increase blood glucose.
I’ve been anxiously waiting for Apple to come up with a glucose monitoring mechanism for their watch, so it just too obvious to me that this is a scam.
I don't know how accurate these watches are with Blood glucose since the one I bought will still give a glucose reading even while the watch is off the wrist sitting on the coffee table! Other reflective sensors like a pulse oximeter will not work if they aren't attached to a body part.
Did you buy this particular watch?
@@DaveTheKayaker The one I have is E500 so no not the same. Thanks for your reviews and reply.
mine didn't give reading without skin contact.
All those numbers and features right or wrong are not having any impact on ones health... but glucose level....?
I stick with my glucose meter....
I think the test that does not seem to work you have to put your arm close to your heart. I know the cuff blood pressure monitor I need to do that before it will work. It would have been nice to test this with a blood glucose meter to see how accurate the readings were.
Dave, vcoffee does cause blood glucose spike due to a reaction to chemical changes.
I am not used to the numbers of bg monitoring, does it have the more traditional usa numbers like Ideal is 100 and low is below 80 and high is above 120.
Same here. Could you please let us know if it can be switched to show the american measuring system for blood glucose levels? Thanks.
Agree..... 60-80 is low/worry.....100-120 might be good......200 might be high/worry...what the heck is 5.74 ????
@@TheWilferch 5.74 mmol is 103 mg
Waking up with high blood sugar is normal. It even has a name the 'Dawn Phenomenon'. The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia.
Fitness gaming is for more interactive games that make you move. Partial thromboplastin time (PTT) is the time it takes for a patient's blood to form a clot as measured in seconds. PTT result may also be due to: Bleeding disorders , a group of conditions in which there is a problem with the body's blood clotting process. Disorder in which the proteins that control blood clotting become over active ( disseminated intravascular coagulation ).
Interesting. Thanks.
Great Review your voice is great brother. Love your review
What kind of sensor this thing since that it profess to measure blood sugar via the skin ?
Nobody has really explained this to my satisfaction yet. It is an optical sensor that detects light reflected back to the watch after it transmits light into the body, then some voodoo algorithm does some sort of signal processing to generate a number. Some sort of optical absorption spectroscopy. Until somebody explains it to me in a way that makes sense I don't trust it. I understand spectroscopy, but I'm not sure I believe $30 Chinese smartwatches are doing it the right way.
Fitness gaming - exercise that is done with gaming consoles such as the Nintendo Switch, Oculus Quest 2, and others.
PTT
Perhaps Physical Therapy Time?
Appreciate your review. ✅👍😊
We've learned it is Pulse Transit Time and requires a chest strap that was not included with mine.
Measured in seconds to clot formation, normal PTT can vary based on laboratory or institution; however, normal PTT is between 25 to 35. PTT ranges are used to classify heparin dosing schemes as low or high intensity and to ensure effective dosing.
Thank you for the very informative content. I’m looking for a watch with this features. Would you recommend this?
My personal opinion is I think the e400 is better for blood glucose fluctuations. ruclips.net/video/4PzzQwqsWQw/видео.html
I stopped watching as soon as you say from AliExpress
I understand totally. BUT you can get some good deals from there for exactly the same watch you'd pay 2x or 3x more in other places. I'm on a really tight budget on this channel so I usually scout out the watch I want to review next and then see if I can find it on AliExpress for less since I know I'm essentially buying it just to do the review and then give it away. I've got the Rogbid Rowatch 4 coming next and then a new surprise on deck after that. Both have blood glucose and the latter has brand new features that I've *never* seen in a smartwatch, so that one will be totally unique. Hopefully the Rowatch 4 review will come out this weekend and I'll have a coupon code for my viewers to save you some money. Thanks for at least partially watching! ;-)
have you considered pricking your finger and testing blood glucose for real to see how this watch compares? not the most pleasant of things to do, but that's how you would test its accuracy ...
I've thought about it, but I don't need to test my blood normally and don't have a kit to do so, so I'm not inclined to go out and buy a testing kit to compare to devices that actually claim not to be medical devices. I don't want to send the wrong message or make any medical claims. I hope everyone understands.
He didn't test it because he knew it is bullsh.t
It is just a toy. And to get a regular testkit is free and you get 5 or 10 Teststrips included. Those company's generate there revenue by selling the Teststrips afterwards. So it was laziness or he knew it will never be similar.
If you have a look 3:25 the glucose level has 2 similar spikes into 4hours. This is impossible because it never falls like it rises and not in that short time

The speed on this video is great.
Body produces cortisol and adrenelin which affects glucose before you wake up.
LOL. The EPT feature measures stimulus. What kind of stimulus? While watching TV, Work Stress, or doing the Hokey Pokey? IDK
What is it used for?
A PTT test is used to check for problems with a specific group of blood clotting factors. The test is done to:
Find the cause of too much bruising or bleeding.
Find the cause of clotting problems. Causes can include certain autoimmune diseases such as lupus and antiphospholipid syndrome (APS).
Monitor people taking heparin, a type of medicine that's used to prevent and treat blood clots. PTT testing can help make sure the dose is safe and effective.
Check the risk for possible bleeding problems before surgery or medical procedures. (A PTT test is not always used as a routine test before surgery. It may be used for certain people who may have a risk for bleeding problems).
Hi does it send a message to the android phone if the sugar levels are out of range?
I would like to reach out this company and see if we can partner to test feasibility and accuracy of using this smart watch as part of doctoral training. Are you able to provide contacts?
No, I have no idea who makes it, but I think there are only a handful or fewer companies in China who make all these low-end devices and then they get branded under different names.
I bought one of these blood glucose watches from another company. I will check it and hope it helps. I saw a video from someone who took blood from both sides of the same finger and got a 30 point difference on a glocose meter so even them are not 100% accurate.
I guess even real glucose monitors have a significant % deviation in them. That said, I have since come to believe the non-invasive smartwatches are not even close. They show peaks of similar magnitude near normal meal times, but do not deviate if you skip a meal or just have coffee or water vs. a full meal. They are not medical devices and should not be treated as such.
Could your blood sugar after fasting be affected by what is known as Dawn Phenomenon?
Yes, that is likely what is happening. I learned about it after this video.
BG would increase after a cup of coffee due to adrenal response, especially if you don't eat at the same time.
Agreed, but the amplitude of the peak should not be as high as a full meal.
This watch is a waste of time,dont wsste your money,poor battery life,and very poor reading of blood sugar.
The blood glocose measures in MMOL, does the watch allow change to mg, which is what we use in the US. I know the F100 smart watch uses a different app, and that app has a feature to change the measuring protocol in its settings from MMOL to mg.
5.7 mmol shown in video is about 102 mg so he is good ! BUT, why didn't he do a simultaneous fingerprick test with a standard glucose meter ? He already knows that MOST everyone wants to see that ? right ? Please do it and repost another video . Thanks ! Also, does it do continuous monitoring and save the results ( I don't think so ).
PTT is likely the speed of the pulse wave. Since it is able to measure ECG and the blood pressure \ pulse by local sensors, I would expect that you also have to press the lateral sensors for that.
If the speed is too high it would mean that the central arteries are too stiff, indicating a higher risk for CVD.
Thank you very much for that review, it helps me a lot.
I have sth else to mention. Of course my observations are naturally very limited, yet... First, your heart rate is quite high. second, you talk fast, third, your fingers tremble if you don't focus on them, fourth, there seem to be issues with your sleep. This points to an overactivation of the sympatikus branch of the vegetative nervous system, OR a specific condition regarding the alpha-2 adrenerg receptors. It can be treated by very (!) small doses of beta blockers ...I suggest you should talk to a specialized doctor
Thank you🙏 so much, appreciate the info.😀
You didn't check the glucose with a standard glucomètre??
No I did not. I did not have a glucometer at the time. Plus this is not a medical device and should not be treated as such .
Got one today 17.04.2023 took my glucose reading it showed 05.16 when i took a manuul reading and that showed a reading of 19.6 ? wt*
ruclips.net/video/zfG4wl_R6Zo/видео.html
Just common sense, how can they read the glucose without the glucose?
Blood glucose in the US is usually in different units, the watch is showing mmol/L but we usually use mg/dL a much higher number usually.
I don't have diabetes, but how do you know what 5.16 reading means in terms of a range say 80-200 on a meter.

Hmm, let the smart dummy speed up replay. Speed OK. I hate when I get Alibaba video where they high speed videos like they do not have MB capacity. Here I woulda preferred seeing the back of watch and a description of what YOU think are the sensors. Or if you coulda found out from manufacturer? Google says PTT is clotting factor, you coulda show a measurement?? Unless it was not working? and did not give a reading?
For use of the PTT mode you need the chest rig. 😊

@@csakijudit2481 Apple is 3-5 years from releasing their BG watch. Please only trust them if you're Type 1 Diabetic.
Hi! I bought mine but when I measure my glucose and blood pressure it will always say “keep still as you can”
Ptt = partial thromboplastin time. It’s the time your blood takes to make a clot, which technically is how fast an injury will stop bleeding.
I believe it is actually Pulse Transit Time
Hello ,what is the best choice of glucose watch ? thanks
None of them.
Obviously a every based review! There's no way to reliability measure BP and BS photometrically on the wrist. Also the ECG coming out with the QRST peaks as shown looks like a too good to be true scam. ECG potentials are in the single digit mV range measured on the thorax with wet electrodes. Impossible to reproduce with fingers touching for several reasons. I think they just use the pulse from the photometry and draw stored ECG sequence which they superimpose with the galvanic potential of the fingers touching. I have developed ECG instruments to know that in this arrangement it can't work.
In other words sorry to say but this must be a scam!
I don't think any watch will do blood glucose because you have to contact some blood within the body
I think you are right.
Thank you I need this
Thank you for posting :)
PTT seems to be the continous measureing when using the chest strap.
That makes sense. Mine did not come with a chest strap even though there was one in the photo.
Yes. You have to buy the accessory version with the chest strap.
According to good ole chatgpt: Pulse transit time is a measure of the time it takes for the arterial pulse wave to travel between two points in the body, typically from the heart to a peripheral site such as the wrist or finger. This measurement can be used to estimate cardiovascular function and has been studied as a potential marker for various health conditions.
Some chest strap heart rate monitors include sensors that can also measure PTT in addition to heart rate, providing additional data for fitness and health tracking

I love the E300, but it does not do blood glucose. For that I prefer the E600. E600 does not do laser therapy, so if you believe in that then the E300 gets the nod.
Can you comment on the number of watch faces available from the app? Also I'm interested in the apnea detection, did you actually have the watch vibrate? And what is your observation of the battery life with all the sensors on?
6 dial faces are stored on the watch and the app seems to have 50 more, plus you can use a custom photo as a watch face. I had all the auto-measurements turned on but did not have an apnea event while testing, so I cannot verify that particular alarm. I easily got 5 days on one charge with the screen on the lowest brightness, screen time set to 5 seconds and lift-your-wrist feature turned off. Plus I only connected to BLE to synch data.
