Your channel is the reason that I haven't got any watch 😂
me too 😂😂
@@hasanaih7429 😂😂😂
Same here 😂😂
Lol,I get you
sad to say apple watch seem to be the consistent one, the price....
I can't tell you how satisfying it is to see your reviews: the data analysis, visual presentation and scientific explanation. You are far far ahead of many of your competitors out there. Keep going!
I absolutely agree with you...
True
This guy set a new standard for sport watch reviews :)
Dude, your channel is the most honest, analytical and comprehensive content. Keep it up!
Another great review, love to see that there still real scientists out there doing research work that can be immediately put to use by everybody. Kudos!
How could I miss your channel until now???
The tests are awesome..
Thnx voor al de reviews, Rob !
Vakwerk en zelfs voor de leek goed te volgen.
I never leave reviews or comments- just wanted to say your analysis is the most in-depth and actionable of all the videos I've searched. Apply these explanatory and analytical competencies across a wide variety of products and topics. You got it.
Love this scientific breakdown ❤️ so happy to find this channel and definitely subscribing to the channel + the newsletter
I just saw that the Fitbit Charge 5 was released recently. I can't wait to watch your video on it!!
talk about comprehensive! this is exactly what I was looking for. keep up the amazing work.
love your videos! so informative and truly helps consumers like me who reads, researches and thinks hundred times before buying anything to make sure it's worth every penny
It looks like this reasonably priced watch might be replacing my Samsung Gear S2. Thank you for the great scientific testing!!! 👍
That's professional review. Thanks for spending your time testing this smart watches. Hope to see the Galaxy 4 on test.
I must say I love your reviews this is the kind of content I enjoy watching with some actual data analysis of the products you are reviewing and not just random opinions, it would be super interesting comparing with other kinds of exercises like calisthenics, yoga, running, swimming, etc. keep up this great work :), and quick question whats of all the ones you've to try wich one is your "do all" pick?
absolutely amazing channel and research , continue the good job !!!!!
Nice job on the review. Much appreciated. Thanks for doing this! Cheers!
I don't understand so much English language but you are new format laboratory about devices, thank you man!
Really satisfying and a gives a good point of view on what's important without getting commercial
From INDIA.
Thanks for video and keep doing your work ❤️👌
Another great video! Thanks making these videos they are very helpful 👍
I've not seen so much effort on a video, as someone from a scientific background I appreciate that
Hi, can you review Xiaomi Mi Watch S1 Active as well? Your review is tremendously informative 👍👍👍
😌🔥 This a Different Category of Reviews, and this is the beginning. Rob you'll be famous because of your empathy. 100% Support. ✌🏻😎✨
I have thoroughly enjoyed your review. I just started working on my fitness. I have learnt about the heart rate zones very recently. Your reviews and insights about accuracy are very much helpful for a true fitness enthusiast. I'm looking forward to see your review on the Oppo watch 46mm which is quite popular in Asia and Europe.
Appreciate your efforts. :)
Love the sleep test results vs other devices!
So glad i came across this channel. Hope you have plans to cover fitbit charge 5 and galaxy watch 4 soon. In need to buy one of them for reasons including ECG and would be very useful to see them reviewed.
Great video as always! Very detailed and useful.. Hopefully you can test the Xiaomi Watch S1 Active soon!
Exactly what I was waiting for.. good review keep going
I agree with others- your reviews are much more useful than the others which are more interested in how many sensors there are, rather than whether they are any use or are even vaguely accurate
I watch your videos before I buy smartwatch because I really need to know about the sleep tracker. thank you for giving us great info about it and compare it with EEG. so helpful
Thank you so much for the review
Thanks for the SpO2 test!
Thank you so much for all of your videos, i know which watch to buy for me and my step dad now ❤️ !
This Chanel is gold.
great video as always! I hope you'll do galaxy watch 4 too!
Great review! I live in Cyprus and only have access to these kind of wearables. If I want others, like the Inspire2, I'll have to import from Germany. I might still do that, but really, after watching a load of your videos mostly I'm just thinking I should get that chest-strapped dedicated heart monitor, one of those finger devices for blood oxygen, and for sleep..... still not sure... probably the Inspire 2 actually :P
Thanks for the review
Your channel is great! Scientific, analytical and on point. However, if you can add your GPS results, it would be PERFECT!
Love your reviews. So many statistics ❤️. Would love to see 4 runs in it too? Maybe 2 X 15 - 20 mins. And maybe some 400 reps! Running is the deciding factor for me.
That was really informative! It will be really nice if you could test the Xiaomi S1
This channel is an incredible find!
Great analysis 💯🔥
Thats a lot of hard hard work. Kudos
Would be really great if you could do one for the Mi S1 active, they made a few noticeable changes in their HR tracking from what i read....Great content as always!!!
Your the best ! Your videos helped me buy a watch !
Amazing results in sleep tracking. Overall pretty decent tracking device, in my opinion
indeed but there is no smart alarm feature which is a downside for such a great device with good battery and overall tracking and functions
@@Bilis123131 smart alarm?!
@@ahambhramasmii don't know if you still care. But he/she probably is talking about the alarm waking you up in light sleep instead of deep sleep, making you feel less groggy
I think that mi watch have it smart alarm
Thank you, it is very helpful
Good job as always !
Waiting for the Galaxy watch 4 review :) i already got my watch 4, and waiting for your review to know how accurate it is 😊
I really have to thank you for this channel, it's just what I really wanted to find and had a hard time doing so before finding your channel! Sounds crazy to compare a fitness watch with a regular smartwatch, but based on your results, would you recommend the Mi Watch vs the Polar Vantage M2? As far as I know the M2 is just a software upgrade over the M, hardware is the same, and whereas the Polar is obviously better in heart rate and sleep detection , I wonder if it's really worth 3x the price. My main use would be to check sleep quality and heart rate while riding a bike outside during the week and mountain biking on weekends. HR data is not precise on any wrist based watch while mountain biking because of the nature of the sport, so I was wondering if it's close enough in the other scenarios.
Awesome review!
You deserve an award
I'll be getting this watch next week, thanks a lot Rob for your efforts I really appreciate it because you recommend this watch over others in same price point which I had hard time what to get.
I just bought it ...but now I got bored and I thinking of selling it 😂
Got the device before your review and glad to finally see a proper review for it!
Btw, what firmware were you on? 1.3.63?
I absolutely love your scientific approach. Nevertheless, since the firmware of those watches is updated every now and then, it would be better for you to specify WHICH Firmware version your tests do refer to ;-) Keep going!
"from time to time" you are still nice.
this is such an amazing video
This is quite a great review.
Thanks Rob.
You had an oximeter on throughout your almost 3 hour flight, just to do this comparison
You deserve a subscribe!
that is a lot of work,thank you
Great video, using this watch after using Apple Watch S6....does the job considering the price
GREAT vídeo and thanks for sharing! I think that you should try now the new Xiaomi Watch Color 2!
Impressive sleep tracking results.
Can you add an R^2 coefficient on your future graphs please? Keep up the great work!
A great review. I enjoyed the feature list at 1:22. However, in comparison with Mi Band 6, the watch lacks pulse oximeter (so I believe it won't measure the quality of my breath at night) and daytime sleep. I prefer the band. (I did watch the review of Mi Band 6 in full). I am looking forward to Mi Band 7!
Would be cool to see a review of the new Xiaomi Watch S1
I agree with the rest that your approach is really refreshing! might i add a suggestion or the HR en sPO2 measurements: perhaps the accuracy would improve if you would wear the watch around your wrist instead of the lower part of your arm.
Hello ,you do a great job really so helpful thank you ,can you please recommand me what is the best accurant smart watch or band for workout ?
Alright, after watching your thorough research and reviews, I've decided to buy the Mi watch. It's been already 2yrs that I've been pondering whether I should buy one and which ones are accurate for sleep analyses, spo2 and step counts. I don't do much exercices so the heartrate being off doesn't bother me. Thanks for your comprehensive and detailed reviews!
1 just bought it 1month ago ...now I am bored of it ... thinking of selling it
@@shrivatsasumant6055 why bored
@@shrivatsasumant6055 you buy a watch to wear it and look at the time, not to keep playing with it
Wonder, does it count steps if you move your hand like stirring something? This is very important to me. My fitbit counts everything as a step.
can you do a review on the fossil gen 5? no one has done a in depth review on the accuracy of the step tracking, heart rate monitor and the sleep tracking before.
This channel is an amazing resource.
Any plans to review the new version of the Xiaomi Mi watch... currently considering an upgrade here :-D
Great review, thanks. What do you think of the Xiaomi Watch S1 Activ, and will you be able to do a review for it as well?
Obviously a man of distinguished taste and knowledge with the X220!
Nice review
Too bad that video came out 3 weeks after I've purchased the gt2 from Huawei. Very nice videos, by the way. Greetings from Manaus, Brasil.
I know it just came out, but id love to see you review the Galaxy Watch 4, it now as bodyfat tracking like a dexa scan which should be interesting
Body fat tracking is unreliable, not accurate and not consistent, dexa included. Do not buy a watch because it has body fat/muscle/water tracking, it would be a waste of money. Samsung just introduced this feature because they could not introduce glucose tracking and they had to differentiate the GW4 from the GW3.
Thank you. Here in Russia fitbit charge 4 is almost 2 times the price (≈200euro), and Sense is 4 times the price (≈400euro). So yeah, not really a good (I mean "equal") alternative. Xiaomi Mi Watch is 90 euro here right now, so, for that price, I think it's perfect overall budget choice.
Hey there is the new galaxy watch 4 out, and it has a crazy feature that allows you to measure your body composition with only two fingers. A review on the accuracy of this would be really cool ! Anyway I hope you're having a nice day, love your videos 😁.
Analysis God or what? ♥
Awesome review! Are you planning to review the upcoming Samsung Galaxy Watch 4?
Very good review! - i have sleep-apnea, and have a CPAP machine, i want this watch, to check my sleep and heart during the night, ordered it yesterday, thanks from Levi in Sweden
If u want I can give you at more affordable price
Damn mi watch, i was almost about to buy you. Make it perfect and approved but by the quantified scientist and i will buy it
Thank you very much Rob, based on this video I purchase the watch. Your scientific review is the most important review compare to other review on the internet, I almost buy the garmin venue 2 also based on your review but since the price is 4-5 times the xiaomi mi watch I purchase the mi watch. At least for this time being.
Thx uuu !!
if possible could you retest a previous watch/band that has been updated wirelessly. since the measurement and calculation is all based on software a simple update could possibly change the accuracy of the device. i am interested in the future update of Mi Band 6 since your tested version was very bad. maybe in the future an update could save it.
thank you very much for your work!
Please please review the Galaxy Watch 4 BIA vs DXA scan.
OK, seriously now, you saved me at least 100 euros (and yes I've watched more than 20 of your amazing videos!). I'm a novice runner (max 5K), needed just basic info like GPS (distance + pace) and an approx heart rate for calorie count. I was looking for Samsungs and Garmins, but let me tell you, for someone that knows what he/she needs, this cheapo Mi Watch is great! I've used it for hiking too and gave the same readings (distance/altitude/steps) with my friend's Huawei GT2. Thanks for all your effort, keep it up, love from Athens/Greece.
Is it accurate for running
@@godza4735 yes it is, the GPS is great
Thank you for this video, can you also get a test for Amazefit Bip U
Your videos are realy great. I like the sientisting side. Please let me know what device is the best ? Or what device I should buy to keep body health measurement ?
Thank you very much !
Thanks for the complete and great scientific review for Xiaomi Mi Watch. Meanwhile, I recently found out that this watch does not support PAI function, which is a very helpful function for anyone who wants to have an overview of her/his fitness, since this function was introduced after Mi Watch's release. So, I think it is better to wait for the next generation of this watch, that would hopefully have all the new functions of Xiaomi bands and watches.
Great video and it's worth it in getting this watch for Christmas however Mi watch color 2 is already released in China then probably they will release a global version so what should I get?
This one or the upcoming version of mi watch and I will hope it perform the same as in this video. Thanks for reading.
I want to thank you very much for your videos. Are you going to do scientific review for xiaomi watch 2 pro and Fitbit Charge 6?
Love your content. Any plans to review the new Xiaomi S1 watches that just launched? I bought the active one so hoping you will review them one day so I can feel bad about all these extra calories I'm fooling myself into believing I'm burning. XD
Cheers
Hi, I hope you can do a test on xiaomi composite scale 2 , which measures body fat and muscles and there is a lot questions on the accuracy
Hi. I love your content. Hope you can do a test on xiaomi s1 active watch. Thanks
Wow what a review
Great channel, suggest you make shorter summary videos (or summarize in the beginning) as many would not want to listen to the detailed analysis but are interested in the results!
I recommend reviewing the new Fitbit Charge 5
Very great job
But you should test the mi watch in a moving vehicle, due to the movement of the vehicle it will flasley indicates higher HR than the normal
Hi from Spain! Great review, congratulations!. I am considering the acquisition of the new version " Xiaomi watch S1 Active". Do you think it will work as the mi watch does?
