Hi Rob! The new mi band 8 is out. And the manufacturer is different from the past generations. This generation is directly manufactured by Xiaomi, while the past ones were actually by Amazfit. I tested the accuracy of its optical heart rate sensor. Compared to my chest strap, it’s surprisingly accurate. Even does not have the 5 sec delay which the Apple watches do. Can you do another comprehensive review of the new Mi band 8?

Other reviewers just read the brochure. THIS is actually a true review. Your efforts are really appreciated.

I see Xiaomi just released the Band 7 Pro a few weeks ago and also a firmware update today that they say adds some features and improves others including heartrate, blood oxygen and sleep tracking. Would really like to see you do a full "Scientific Review" of this Band/Smartwatch in the future if you can. Thx for all your hard work!

This review is absolutely ridiculous and incredible in equal measures. This truly is an amazing and in depth review. With a level of detail and accuracy that I have never seen anyone produce on youtube before. Instant sub and notification bell click.

This is GOLD! Thank you for all the hard work done in all your evaluations. Looking forward to an in depth review of the Mi band 7 Pro.

Thank you so much for this review! Made me go for this product, and I keep coming back to your video. I needed a device that's small on the wrist and tracks fitness data with reasonable precision and can help me gauge my sleep stats (primarily deep sleep) so I can understand how to sleep better. The fact alone that this records steps, distance, heart rate, and deep sleep accurately enough for a layman (coupled with my phone, it also tracks my exercise routes super accurately) is perfect for me in and of itself and this device has so much more to offer in terms of notifications when you reach your steps goal for the day. It tells you when you've been sitting for too long, has guided breathing exercises with vibrations on your wrist to help you calm you down, etc. I also have vibration alarms that remind me to go to sleep at a regular time and help me get up in the morning (without bothering my girlfriend!). Most importantly, this device is discreet and helps me gamify my daily exercise, making me walk more and and make an effort to stress less, and it generally gets me stoked to take better care of myself. I like wearing a classic wrist watch as my main watch, and I can just put this on the opposite wrist and turn off the screen. It's light and sleek enough that I don't even notice it's there. Also, the screen is awesome. Highly recommended!

I really love your video's. The quality between your reviews and others are huge! Thanks so much for all the work❤

What activity did you test it with?

I have had the Mi-Band 7 for a week and finding it awesome given its price point. Your research helps people understand the watches better. Thank You.

I've discovered your channel on last weekend and immediately got addicted to your videos, I love this kind of analysis. Thanks for yout amazing work!

Thorough coverage. I have been using an Amazefit Bip for several years and was a bit disappointed to how poor it compared to other similar devices. So this review made it clear that I should consider replacing it. So I will subscribe and make up my mind on the basis of you reviews and my specific needs. One note, I don’t want something like the Apple Watch that requires daily charging. I really like the Amazefit I have because it goes for weeks. Thanks

highly undervalued channel. Never have I seen such organized and scientific review for just an random cheap smart watch. Thank you for all your Effort. Continue and I know your gonna grow till half a million at least!

Love your content. your videos helped me choose a device with much higher confidence. Here's an idea to quantify the accuracy of the GPS data. Export your GPS data on the map as a png (Screen clipping should work), then with a digitizer tool such as webplotdigitizer, get the x and y coordinates of the tracks with a predefined spacing. For the reference, use a predefined route, drawn on the map or imported, then export the coordinates with the same spacing values for both x and y. The difference between two data sets should be straight forward from there. Admittedly, this approach doesn't include the time variable of the acquired locations for the track. But probably, that does not matter much as long as one data point at a stationary location can be confirmed that was acquired within a reasonable time frame. Let me know what you think if you read this comment.

Yep, I’m buying this one. God bless you for the great efford you put into these reviews. Looking forward to see your videos in future 🙂

Glad I found your channel!! The effort involved in the video is insane!!! Subbed!

Thanks for making such great reviews!

Thank you for another great video! I'm doing the rounds on your videos trying to find a fitness tracker thats best for my needs since it is my first time buying one. You're certainaly giving me lots of great data to use!

Just found out about this channel and I’m stunned! I wanted a review on the miband but other than that I love statistics and statistical analysis! Great content, keep up the good work

Hi Rob, if you want to know what the stress calculation might be search for 'baevsky stress index'. The info page in the stress widget clearly says that the calculation / measurment is HRV based. The baevsky stress index was developed in the 60's for astronaut health tracking.

this is amazing! very informational, thank you very much for this video! Subscribed!

great video! I'm looking forward to the promised full review, to see if they've corrected the inaccuracies via the update - as well as a scientific review of the MiBand Pro.

Great video as always! Looking forward for mi band 7 pro scientific review next! 😄

I was so impressed with this review I subscribed. Outstanding job!

Thanks a lot Rob for this promising outlook. Eagerly waiting for the final report. Also a question if you don't mind: is the xiaumi s1 watch (active) on your radar?

Came across your video while contemplating whether to buy this device - thanks for the effort and for providing such unique insight into how these devices perform for people with different tracking needs!

Thank you for your vidz. Your visuals are great, speech is well paced and easy to understand.

Dude, this is what i have searching for a lot of time, every video who i see is about comparatives of the apple smartwatch, but no one is with medical things, you have won a sub! :)

the review is very helpful!! I hope you do a review on mi band 8 next!

Wow all efforts testing different watch with actual scientific devices is a THUMBS up. Thankyou so much

Thanks for the review. Do you have any webpage with comparisons and overview of different products?

the amount of work you've put in the video.. respect man!

I was waiting for this video . Thank you!

I got this thanks to your review, it's already had some new updates which is good:) the Spo2 seems very accurate. it also can be left on all day which suits me well. thanks again

That's how a review should be made. Awesome content!

Your Signal-to-noise ratio is excellent, many thanks.

Hi Rob. Just a question. Does it make sense to wait for the final Mi Band 7 review that you announced months ago? Appreciating all your work and efforts.

Useful as always! Thank you. Please review the new mi watch s1 soon. Can't wait to know if it's any better in accuracy

Loved the channel, you really take it serious Gonna wait for part 2

Excellent review! With this video, all my doubts of these smartbands has been scientifically answered. Thank you Sir!!!

Really like the look of this new watch. The screen size is spot on.

You seem to love watches (and science) - I think a fun project could be reviewing scales like those from xiaomi. There are part of the self-tracking ecosystem and have so many datapoints to look into. Cheers for all your reviews so far 👍

You are one the best gadget reviewer I have ever seen in you tube. Very convincing with lots of measurement data.

I was waiting for this vídeo. Thanks! ✨

Rob, you are my favourite smart watch/activity tracker reviewer. Very friendly and clear explanation. 4 thumbs up 👍👍👍👍

Does the mi band 7 allow the use of its timer app while monitoring workout eg Freestyle training or Indoor fitness at the same time? Great video! Amazing video, love it!!

I have the MI band 5, and love it. I really like the sleep data, like resting heart rate. I love the PAI data also!!

I really appreciate the quality of the review. The results of the heart rate tracking during exercize is worse than I expected. I guess I'll have keep my apple watch 6

Hi Rob, Excellent video! What is the next werable to test?

Finally a review with acual information that is helpful. Normaly reviewers just read the specs

Very thorough and helpful. Thanks!

Hey, loved the scientific approach. Would you be interested in doing the same research for Xiaomi Mi Body Composition Scale 2 tracking accuracy? Or are you narrowing the focus to only watches?

You helped me to decide and buy the band, I know it's not perfect or the most accurate but for the price and my goals, it's good enough, thank for your input, cheers from Ecuador!

Hi! Thank you for the scientific review! I appreciate it sooo much! I had to let you know that the Mi Band 8 is out, but in CN Version for now. Global Version are rumoured to be released by end of 2023 but we'll wait and see. I'll be waiting for your review on that before getting one. Thank you for all this amazing efforts for the reviews 😊✨️👍🏼

Thanks so much for your detailed and metric based reviews! After watching your review, I decided to buy this as my first activity tracker. I owned the vivosmart 3 for a few days before returning it, does that count? Anyway, I see that the watch has an option to enable "detailed sleep tracking" requiring extra power. When testing, did you have this option enabled? Did the option even exist in the firmware at the time you tested?

Good review, as always. I would like to see your take on PAI health points system one day. It's on this and other xiaomi bands.

Estaba esperando este video, muchas gracias

I just stumbled upon your channel and I'm mindblown by the effort and precision of your reviews!

Extraordinary analysis. Many thanks.

Thanks for the review. Could you please include to the next video a heart rate measurement accuracy after running?

Amazing videos, especially with the amount of scientific analysis you do on different products to let the consumer what's the best wearable for them. :D If you don't mind, could you do an analysis of Pebble Cosmos Luxe SmartWatch? Thank you :)

I was waiting for your this video. Thank you.

there are 2 things I like about mi band over huawei band 6: higher screen dpi, stronger vibrator and better compatible with iphone (music control and some small stubs)

Great review as always 👍. When can we expect a review of Huawei Watch Fit 2 ? 😁

Wanted so much for this review, i hope xiaomi fixes the HR issues with firmware updates. Just a question, can you imagine why most watches struggles specifically with the rem sleep of the sleep tracking?

@Spacemonkeymojo

2 жыл бұрын

I would say it's because REM sleep would be hard to quantify based on a wrist-worn health tracker. REM is characterised by brain waves, something a wrist-worn tracker can't track. REM sleep might affect heart rate or HRV but the effect is probably similar to deep or light sleep, which is why fitness trackers tend to get them mixed up. Maybe something else like skin temperature or something changes during REM, which could be tracked, but that would require the tracker to have a skin temp sensor which I don't know if many actually have. Sucks because I would like to track my sleep stages, that headband Rob wears looks like a good investment for those who want to track their sleep stages.

Notice that MiBand 6 was much better than Band 7 for HR. The 7 does need improvements in firmware to match algorithms with specifics of the sensor, it seems.

Love your work, thanks! Can you do one Amazfit Band 7 review?

Very detailed. Very interesting. One intractable problem I have experienced since the mi band 5 is that whenever I swim it counts steps! If I swim for one hour it will track the swim quite accurately but also will count about 5,000 steps.

Your reviews are one of the best out there. I hope you can also do a review of the new mi band 7 pro and xiaomi watch s1 🙏🏼🙏🏼🙏🏼

Thank you for the review

Glad someone is reviewing the accuracy. This is the real question.

Love this channel! Would be great to see if the firmware updates fixed some of the issues. Especially interested if the sleep tracking and outside heartrate improved. The firmware updates usually only indicate 'fixed bugs' - so that doesn't tell you anything. Probably a lot of work, so can understand if for such a cheap device it is not worth the effort. Subscribed!

Wow awesome. Thats some dedication bravo.

Another great video! Do you have any plans to test the new Garmin Forerunner 255? Your Garmin videos seem to do well with views, and this device generated a lot of excitement because it includes a lot of the higher-end functions for $350 (plus the inclusion of the S model for smaller wrists). Thank you for your dedication to this channel :)
