This is how biometric devices should be reviewed! As a physician, I truly appreciate how unbiased and comprehensive the review is. Subscribed.
Lol, i thought you left that job for becoming musician.
thx
I thought you're an astronaut?
Do Redmi 3 please if possible!
I also wanted to say thank you for your great work! It's super informative and helpful
Hey Rob, just wanna say your content is a breath of fresh air in a world where so much is anti-science and anti-reason. Your objective analysis outshines everything out there for products like this and it really helped me pick a health tracker. Keep it up!! I'm not even looking to make a purchase anymore I'm just watching these because it's interesting. Would be really cool to see more about what you're finding with your data and how it's informing your decisions. I think you could really help people who aren't quite sure how to use these devices to benefit their lives.
This is exactly what I was looking for. Thank you.
Thank you for the review of these devices and now I got mi watch because of your recommendations.
I appreciate the level of production you put into your videos, amazing! ❤❤❤
Thank you so much, I really appreaciate your professionalism.
This vid is amazing and is exactly what I'm after. Thank you! I'm also keen to understand GPS accuracy and reliability as runners have mentioned speed inaccuracy as a dissatisfaction of other smart watches. Any advice?
Great channel, congratulation! Based on your reviews, I bought a Fitbit Inspire 2. Seems accurate on sleep and heart monitor, but it also has many shortcomings. I am also looking into buying a Xiaomi product, but right now can not decide between the Redmi Watch 2 Lite, the Mi Watch and the Xiaomi Redmi Smart Band Pro. I would choose the one that offers the best sleep and heart monitor in this order of importance. (I know any will be lagging behind Fitbit, that is why I bought it first.) Hope you also review the Smart Band Pro and do a comparison between the 3 (or 4, including the Band 6). From your reviews it seems the Mi Band 6 is the least accurate. I wonder which is the most accurate and would buy that.
your videos are life savers, thank you !!
Salute to you for doing all this hardwork
Eternally thankful for your channel! I've probably spent about a hundred hours just watching and rewatching your videos trying to find a tracker or watch that fits my needs. Any chance you'll review the Maimo Smart Watch (that's backed by Xiaomi)?
I'm very impressed with sleep tracking of this device. I'm wondering if the Poco Watch also have this quality of sleep recording, since it is the global version of Redmi Watch 2 (not Lite). Thanks for your amazing work!
I appreciate your focus on the actual function of the device in reality, and not on the features, which everyone can read by themselves anyway.
How about testing one or two of those cheaper Aliexpress smartwatches? Are these just toys, or do they work a well as the big brands?
Great review I've bought poco watch which is slightly updated redmi watch 2 and this review gave me a good understanding of its possible shortcomings. It's a little small but AoD is great and watch makes my forearms looks massive so I guess it's a plus lol
Thanks for also doing reviews on cheaper brands. My budget is sadly limited but my doctor has advised me to at least get good sleep as i have a lot of anxiety as well as health issues. I'm afraid of spending too much as i need to save as much as i can in case i get hospitalized again . The good thing is that so far I'm okay and eating healthy and trying to lower my body fat % as best as i can.
Thank you, i am considering buying it
Nice job, I bought the Huawei gt 2 pro after watching your review. I’m waiting your review of the latest Huawei Watch D . Happy new year 2022
Great video, as always!
AWESOME THANKS ROB
Thank you for this honest review
Good as always. ;) Merry Christmas by the way.
Hallo Rob it was perfect job again, I would like to watch a video to compare First 5 smart watch which is the best accurate. I hope you will do soon.
enjoying watching your videos, just want to know what is the best smart over all until now that you personally recommend ? (beside the Apple watch)
Thank you so much, just what I wanted to find, Facts, I have been thinking of buying a watch, but I find very little research, I know the blood oxygen sensor works differently from the finger probe unit, , I will then look rather for a cheap one, just for the experience, thank you kindly, Ray
You said better things about mi band 6/7 or huawei 6/7 but all of them had worse performances on your tests. I didn't understand quite well, can you review it again? Your channel is amazing!
Love your videos! Please keep the good work. You should do an smartbands/watch Top Tier List
Agree
Awesome videos! Thank you for the reviews!
Could you try the redmi smart band pro please?
Amazing review, thanks!
Fantastic work. Subscribed
Thank you rob❤
Huaweu GT3 pls 👌
thank you for the intensive review =)
Thanks for this video. I'll be getting the Redmi Watch 3 Active now. Is ar 25 USD now.
Hi!
I recently found your channel, and it's exactly what i was looking for!
However, i have a question that maybe you or some of your viewers can help me out with.
So, i live a relatively active lifestyle. I do mountain biking and parkour (strange combination, i know), and my job is somewhat physical too, that involves 20-40km of commuting on bike, plus several hours of walking, stairs up and down, bit of climbing, squatting, etc. Although it's usually only about 2 days per week, but anything you do for 4-8 hours can be tiring.
And well, as i'm getting older (i'm 29 now), i have to think about managing my time and energy a bit better. It's nice to see that these devices are getting more and more accurate (although still far from perfect), but even if we assume they're accurate: are they actually useful? Can they help to avoid overtraining/underresting? Can i use them to guide me a bit by tracking my all day activities, and maybe know when to rest more, or when can i push a bit harder?
Although i was racing for about 10 years, i don't use any metrics for mountain biking anymore, just go by feel. I like this freedom, and i don't even plan to follow any kind of training plans, heart rate limits or things like these. Still, it would be nice to know how much rest should i have, when do i get too exhausted.
Sadly, as i've heard, cycling is not really good for these wrist based heart rate monitors because of the vibrations from the handlebar. And parkour... well, that's really intense and versatile and i'm not even sure i would like to wear a several hundred euros watch while jumping around :D
What can i do with all these data if i don't have a coach degree? Would it make any sense for me to have a sports watch (a garmin, for example), or they're not "smart" enough for my kind of lifestyle? Would they be able to help me manage my energy/stress a bit better?
I know it's a lot of questions (and a long text), but if you could give me any tips or guidelines, i would be really thankful!
Hi may i know which one is better between redmi watch 2 lite and huawei watch fit in your opinion? 😀
Hope to see you test the Ticwatch Pro 3 Ultra
Hello Rob how do this compare to Huawei fit watch
Excellent video
Huawei watch GT3 please. , waiting your review so I can decide if I wanna buy . Thank you
Rob which watch does not overcount steps?
Can't help but wonder how much more they'd have to spend for better sensors to get appreciably better data.
Thank you Rob for the review, just a question what about the accuracy of step counting?
Good question. I imagine that it should be good considering it has GPS... at least you know that you walked X meters and each step is on average Y meters, so it shouldn't be too bad.
Hello, please tell me what is the battery like. How many days can one charge take ?
Have you reviewed the Amazfit Neo yet? You posted on your Instagram a while ago that you'd review it, but I don't see a video for it yet. I'm curious to see how accurate it is compared to all the other fitness trackers.
Does this one have the best precision under €60? Looks like it, if not it should be very close.
Mi watch is only €40 more, but you can also see it as being 1.6x the price.
Hello, i have a question: i have a heart condition where i have a really low bpm around 30-40 in rest. I really would like to have a smartwatch who can measure it good enough for a basic price. I already tried the amazfit gts 3 and it was terrible for accuracy it was never close in detecting my actual heartrate. Do you think the redmi is a good choice for me or dou you have some other good and not expensive alternatives for me?
Thanks, man
Hi
Can you check the oneplus watch?
Awesome review, can you plz review redmi smart band pro?
Bought one for 35$, i use it mainly for running.
good gps accuracy and heart rate monitoring (need to be snugly fit while running)
How do you change the units from Km/Celsius to Miles/Fahrenheit?
When you delete a notification on the watch, does it gets deleted on your smartphone?
Very good information, thank you for the complete review.
Could you please review the Redmi Watch 3, i'm dying to replace my mi band 5 with this one, but i want to know whether the health tracking features can be count on.
Thanks
Wait for redmi watch 4 if you didn’t get the 3 yet. 😅
Budget smart watch, amazfit bip u pro test?
Thx rob , what about Mibro watches ?
Obsessed with sleep in all your videos.
Are you ever review Amazfit Neo? I can't find video about it in your channel
Pls test Redmi Smart Band Pro. Thank you
i cant understand are huawei gt2 pro - are worst sleep tracker on 5:10 table ?
Please do a review of the new Xiaomi Redmi watch 3, very soon 😊
Hello Rob I always watch your videos and would like you to test the new Amazon Halo View fitness tracker, I would like to buy one for my mom.
Awesome! Pease do one on Amazfit BIP 5 with all its sensors for sleep, stress,oxygen, heart rate and bp. Thanks!
Hey Rob, excellent video. You will do a Poco Watch Review?, many say that it is the same as this redmi watch. But I would like to know if there is a difference in terms of the sensors and their parameters. Greetings!
Second
Sleep stages are not that Important to record if you are concerned with circadian rhythm. Estimating and recording sleep start and wake times should be covered.
How is this compared to the Amazfit Bip U Pro?
I hope you can do a review on Garmin Forerunner 55. cheers!
how do i make the app show the diffrent sleep stages mine just a vertikal line with colours
Please make a similar video of redmi watch 3!!
best review of watch
Subscribed bro.
Huawei Watch GT 3 please!!
Naps are tracked?
Hi, I was as surprised as you at the results for the Huawei Band 9. I just spotted the Redmi Watch 4. Any chance that will receive a scientific review?
Bought it for $12 to count my steps and basic activity.
Wow wow!
I'm facing ghost touch issue how can I improve that 😢
Awesome video, i am torn between this and huawei band 7, any thoughts? Thanks!
Huawei band 6 or watch fit or watch fit "new" performs well
do you plan to do mi band 6 update?
I'm considering between mi band six and huawei band 6, mi band is 10 bucks cheaper. Based on you review, I'm considering huawei, but since there is new firmware update for mi band 6, I'm not sure now.
I am in the same. Please tell us about the news you find. Thank you!
Wow buen video, sigue así amigo
I bought the Redmi Watch 2 Lite to practice windsurfing. However in training modes "sailing", "kite surf", "paddle board", "car race" and "kayaking" the GPS does not come into operation. The only outdoor sports that GPS works with are hiking, outdoor swimming, outdoor running, outdoor cycling, trekking, and trail running. It would also be better if the watch could display the instantaneous speed for these wind & water sports. It is a valuable information at the moment of training. And a device that has a standalone internal GPS should at least show the geographic coordinates on some screen. It may be useful in an emergency situation, when your windsurf equipment is broken and all you have is a waterproof vhf radio and the watch. When data from Xiaomi wear is transfed to Strava, "outdoor swimming" loses GPS data and is turned into "indoor swimming". A Bug to be fixed. Another outdoor Training modes that is NOT possible to activate GPS are: "water skiing", "water polo", "other watersports", "rowing", "powerboating","rafting", "ice skating", "horse sports", "paragliding", "parkour", "rock climbing" and "ATV". I have posted this feedback in Xiaomi forum, and they expect that the issue will be resolved in upcoming firmware updates. My firmware version is 1.1.98
Yesterday Xiaomi released a new update firmware for Redmi Watch 2 Lite, but unfortunately the related issues were not fixed. The firmware version was 1.1.98, and now is 1.2.106. I can not figure there is a consumer satisfied with whatever outdoor sport mode that has no GPS activation. I hope hear better news from Xiaomi soon.
Hello, please can you test the new Redmi Watch 4? Thank you! 👏🏻👏🏻
Pls, do it on Garmin instinct tactical, thanks
Redmi watch 3 and 4??????????????
Bro kindly review redmi smart brand pro
Please test REALME WATCHES also
Can you test the Xiaomi S1 watch and realme 3 watch ?
Thanks for the review.
Just need heart rate and GPS to record the distance for jogging, and your review showed the accuracy of heart rate is quite OK (compare to polar).
Will buy it.
Huawei watch gt runner pleaseee.. i'll be waiting.
Can I install games on rddmi watch 2 lite?
HUAWEI WATCH GT3 PLEASE~~
From God's own Country..Kerala..India...Subscribed👍❤️❤️❤️ Ur Efferts makes me to subscribe 😉😘😘😘
Thanks Ragith!!
@@TheQuantifiedScientistFirst I am thanking once again for ur Amazing Efferts!!! I am very confused because my main preference is gps accuracy its testing is missed in ur video...but i got the details from others..But all the other analysing I needs ur video...So I am subscribed...Will u help me by answering my question
If i give these 2 watches and ask to take one..which one should you buy?
Gts2mini , Mi watch2lite ? which is more accurate (NB:Not consider display performance)?
My experience with this watch is a catastrophe:
- totally random sleeping tracking. My mi band 5 was much better
- A lot of lag, the cpu is very weak
- the ring system often stays active for 10 min
THANK YOU SO MUCH!
I'm not happy with the step counter of this watch, it needs my arm to move back and forth to count steps so if I have my hands in my pockets or if I'm carrying something my steps are not counted at all. Considering I don't move my arms much when I walk I miss A LOT of the steps. This makes me so sad because I really like this watch and the design
Plz review of redmi watch active3
if my budget is around this category.. is the redmi watch lite okay? mi watch is still a bit pricey for me..
Do you mean the Watch 2 Lite?
Realme watch plz
Which watch is better in accuracy redmi watch 2 light or huwaei watch fit?
Redmi Watch 2
Huawei watch fit better in HR
redmi watch 2 light better at sleep tracking
Well one doesn't have the money to purchase Iphone & apple watch while rest all have poor accuracy. What is the best band under $100? By best I mean most accurate
I hope when redmi watch 3 got reviewed, it would improve from this
