This kind of videos will always keep the Smart Watch companies on the run. They will think 50 times before giving false information to customers. Thanks a lot man! I really appreciate the video.

[@TheChocoSama]

This is just what I was looking for! To me, this is a highly detailed search and you have presented its results in a perceptible, convincing way. I just loved how collected and organised you are (also polite). Keep up the good work sir!

[@TheQuantifiedScientist]

Awesome, thank you!

[@lucutes2936]

Indeed

[@denislavvalev4282]

Probably my first comment on youtube. Thank you so much! Exactly how accurate the bands are has always been an interest of mine. I've been looking for similar videos or online comparisons forever and no one is doing it. Keep the work!

[@TheQuantifiedScientist]

Thanks for commenting Denislav!

[@koya__kim]

I was thinking of buying my first fitness band, and I thought Mi Band 5 would be a good entry level device. I scoured KZbin for reviews, mostly just unboxings.. and I stumbled upon your channel. Very amazing well thought-out analysis video. You have a new subscriber, sir. Keep up on these quality or dare I say quantified videos. Have a nice day

[@chakree100]

I’m a researcher myself in wellness tech, thought of making a similar style paper and u absolutely nailed it! Keep it up u r doing a really good job! Huge companies like Apple, Fitbit and samsung have become so overpriced in the name of accuracy, precision and reliability. Good job I’ll suggest this channel to people who are interested to buy new fitness trackers

[@janisrubuls]

Interesting and professional review! Thank you for the great info!

[@DSTWizz]

Thanks so much for this! I bought a Mi-band 5 only a week ago (to replace a Mi-band 2 which fell off), and so far my experience matches yours. Altogether it seems to be much more accurate than the old model, but I haven't checked it while cycling yet because of the bad weather here in the UK. My step counter seems very accurate, but I haven't checked the heart monitor when doing vigorous exercise yet. Some other features of the and are very useful too (like reading notifications on the wrist, etc.)

Awesome, thank you Yuri!

[@Rugiada1035]

Loved it! Scientist here too, so seeing something so well made feels great! I was wondering how results change when using the MiBand with a different tracking app, like "Sleep as Android" for night sleep and "Notify for mi band" for sleep, steps, and workouts. I prefer the latter over Mi Fit as it allows to change so many settings, even the heart rate sampling. I suppose each app applies a different raw data elaboration, which makes it really interesting for me :)

[@GustavoLuizGuerios]

Awesome video, I really like your cientific approach. I'll keep following you

[@HariShankarHP]

Exactly how a review video should be. As many commented, most of the review video is all about unboxing and what they think after a day's usage. Thankyou so much for the awesome video:)

Excellent review! I appreciate your empirical evaluation. My doctorate is in machine learning, and I've always had difficulty sleeping, so automated sleep scoring is very interesting to me.

[@romanliebl1914]

Great Review! Thank you being the only Reviewer, that makes thoose sience backuped comparisons. Could you please do a comparison with the Garmin Fenix 6? As it is known to be one of the best Sportstracker / Fitnesstracker at a high price point and all the reviews I have seen so far are kind of subjective when it comes to sleep / heart rate / steps and other metrics.

[@unreal9823]

Great Idea! please do this!

[@rachitajitsaria1254]

Great vid. As you mentioned, false positive in steps tracking is also important to test and also maybe how well they perform after say a few months to understand if the sensors are still accurate. Also, as you mentioned data on other people would be helpful. Many people believe that the heart rate tracker tech performs badly on people with darker skin so would be interesting to see the variability there.

[@trooper2708]

Wonderful explanation

[@francobellomo9979]

Hi, I really liked your video as I am looking for a good cheap sleep tracker. A tip that I read in several places is that the heart rate can be affected by light, so there are many people who put a scarf next to the wrist to block the entrance of light to the watch.

[@androcarot9288]

You deserved the sub, video is great and I haven't even finished it yet.
