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 :)
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!
Love this scientific breakdown ❤️ so happy to find this channel and definitely subscribing to the channel + the newsletter
Dude, your channel is the most honest, analytical and comprehensive content. Keep it up!
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?
How could I miss your channel until now???
The tests are awesome..
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 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
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.
It looks like this reasonably priced watch might be replacing my Samsung Gear S2. Thank you for the great scientific testing!!! 👍
absolutely amazing channel and research , continue the good job !!!!!
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. :)
Exactly what I was waiting for.. good review keep going
Another great video! Thanks making these videos they are very helpful 👍
Nice job on the review. Much appreciated. Thanks for doing this! Cheers!
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 ❤️👌
Thnx voor al de reviews, Rob !
Vakwerk en zelfs voor de leek goed te volgen.
😌🔥 This a Different Category of Reviews, and this is the beginning. Rob you'll be famous because of your empathy. 100% Support. ✌🏻😎✨
Great video as always! Very detailed and useful.. Hopefully you can test the Xiaomi Watch S1 Active soon!
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.
I don't understand so much English language but you are new format laboratory about devices, thank you man!
Hi, can you review Xiaomi Mi Watch S1 Active as well? Your review is tremendously informative 👍👍👍
great video as always! I hope you'll do galaxy watch 4 too!
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 😊
Thanks for the SpO2 test!
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
Great analysis 💯🔥
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.
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?
Thats a lot of hard hard work. Kudos
Your the best ! Your videos helped me buy a watch !
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
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.
Love the work you put in your videos. +1 sub
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 😂
This Chanel is gold.
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.
Awesome review!
I've not seen so much effort on a video, as someone from a scientific background I appreciate that
That was really informative! It will be really nice if you could test the Xiaomi S1
Thank you so much for all of your videos, i know which watch to buy for me and my step dad now ❤️ !
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.
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
This is quite a great review.
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
Your channel is great! Scientific, analytical and on point. However, if you can add your GPS results, it would be PERFECT!
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
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!!!
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?
Thank you so much for the review
Thanks for the review
Awesome review! Are you planning to review the upcoming Samsung Galaxy Watch 4?
this is such an amazing video
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.
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!
Analysis God or what? ♥
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.
You had an oximeter on throughout your almost 3 hour flight, just to do this comparison
You deserve a subscribe!
Great video, using this watch after using Apple Watch S6....does the job considering the price
Impressive sleep tracking results.
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
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.
Can you add an R^2 coefficient on your future graphs please? Keep up the great work!
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.
I was waiting for this review so much. I was having a dilemma deciding whether or not to purchase the mi watch, looking at its accuracy in most situations, I'm absolutely going for it now!!
Thank you!
Why.....
This channel is an amazing resource.
Any plans to review the new version of the Xiaomi Mi watch... currently considering an upgrade here :-D
I just bought it yesterday because I like the functions,the look and the reasonable price.I want to watch your review first ,but It’s been awhile since it came out ,so I think you might not review it.When I saw this video,I feel nervous a little bit lol.Fortunately,it performed quite well.
Does the watch have media music controls? Volume control?
Please tell me about heart rate, many reviews sad its bad even in resting heart rate it record pretty high, thanks for reading.
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 😁.
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.
Obviously a man of distinguished taste and knowledge with the X220!
Nice review
The results for the sleep data here are relatively solid. Xiaomi claims the S1 series is 35% more accurate according to their own study. This bit of marketing seems highly suspicious to me. Even if the improvement is only half that, then that would be tremendous at that price. What is your knowledge of or sense about this claim? Any plans to do an S1 test or comparison test? It would also be nice to know if the SpO2 has become reliable.
I am waiting for the s1 tests also
@@Paladin53 I decided to pull go for it. ....it was a mistake! It's an oversized fitness band (not really a smart watch) and a bad one at that. The appearance of everything meets expectations, but the substance, data detail, accuracy, and functionality are all missing. I can't see that any of the results other than perhaps the step counter or GPS tracking are accurate to a useful degree. The sleep data appears to be entirely based off of heart rate (which is a flawed model), and there is no indication that the heart rate tracking is any better than Mi Watch, which was ok, but not excellent. I can't recommend this "watch" if you care about the data quality, and I can't recommend it if you want other features (there basically are none and there are no apps that work with it because it's a proprietary OS). Two thumbs down! I'm going to sell mine or perhaps donate it to The Quantified Scientist.
@@bmannering thanks for the info, i will check the huawei gt3 at mall. these two were my finalists , and you eliminate the s1
Would be cool to see a review of the new Xiaomi Watch S1
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.
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 ?
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 vídeo and thanks for sharing! I think that you should try now the new Xiaomi Watch Color 2!
Thank you, it is very helpful
Thanks for your videos.
I have 1 Question....
When you are measuring the steps....are you outside with the GPS on? Or you have the GPS off and you are measuring the total steps in general?
Thanks.
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.
You deserve an award
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 !
Thank you for the scientific and so micro detailed review.
I had ordered to purchase this smart watch but due to inability to tracking day time and nap sleeping , I canceled the order.
The important thing that I didn’t find it in any other website and reviews
Thank you again so much
I really hope mi watch can track day sleep, but it doesnt
Have you got any recommendations on any watch or band reading body temperature?
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!
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
Which one do you suggest to buy between the Huawei GT 2e and the Mi Watch? Thanks a lot!
👍 nice review. Waiting for galaxy watch 4 release/review
Coming soon!
Hi Rob, which is best watch for Blood Pressure? Please reply
Thanks Rob.
Could natural light be a problem for the pulse sensor Rob?
that is a lot of work,thank you
Could you compare a dexa scan vs the galaxy watch 4?
Hey, did you review the Mi Watch S1? If not yet would you mind doing so, in comparison to this, Mi Watch?
