As someone with multiple degrees in exercise science, I am loving the analysis of these trackers. This is significantly more insightful than other reviews which really only tell you the features, and nothing about the efficacy of the device they are trying to make you buy. You really should have more subs.

I bought mine band7 a few days ago, and was wondering if it was really that good, your video helped a lot, never saw any reviews like yours, you’re the GOAT man, thx for the help!!!!!!!

I'm not a fan of wearable tech, but I needed a watch that's under 60 euros for tracking my activity, and seeing this perform better than the whoop which is very heavily sponsored and much more expensive , I'm happy with knowing it's not going to be a bad performer. the detail in the video is incredible so thanks for putting it out there !

Just found your channel. I'm planning on replacing my Mi Band 5 and I've binged several of your reviews. My Mi Band has disappointed me a lot, especially since they changed the app (from Mi Fit to Zepp Life). I've found your channel to be highly informative. I hope Huawei addresses the sleep tracking issues since I'm in love with its HR and step counter features. Never thought Amazfits were that bad, considering how good they look. Thanks for the info 👍🏾

OMG, this is by far the best scientific testing of smart devices so far!!! this channel is very underrated.

I own the Huawei Band 6. Glad to see that it performs slightly better than the Band 7

The mi band 7 has just been announced, so I will hold myself back until you review it. Good content.

Im following your video for about 1 year ago and thank you so much, even im not buying smartwatch/band every single product release, your video still entertaining for me, keep up sir !

I want to add about step counter. Huawei apps also count steps taken by phone sensor. It would be great if you do both: with phone in pocket and without phone at all to check if it's more accurate if the phone is inside pocket

im so happy when i find a review from this channel for a product im considering, the effort put into every video is amazing

Thank you so much for this review! Im looking forwad the Huawei Band 8 when its coming :)

Thank you very much for your videos. Watching you from Ukraine. You make a very important tests and unique content. Take my like :) Ps during last months I realized that physical training helps to stay in charge even in the most difficult situations. So if someone of you have difficult times or depression - please just go for a walk on the street or visit some gym near you. It really helps.

I really appreciate your hard work, quality content and I must say you help people make a better purchase unlike the other KZfaqrs whom smack features and read pamphlet from the manufacturer, thank you

This guy made me believe in scientists even more. I'll def get a band 7 now :)

I'm surprised Band 7 didn't outperform Band 6. That's a pity! Still, there is a chance after updates Band 7 performance will be improved Thanks for a great review!

99% review... 1% self promoting Love it💓💓💓💓

It's good to know there are still people like you on youtube, thank you

I love and appreciate your work in analysing the accuracy of modern watches, but I made an astonishing experience, that might be worth to think about regarding sleep tracking. When checking your experience of sleep tracking of the Amazfit GTR3, that watch is pretty perfect (and even better than the Withings Sleep Analyzer) regarding only the total or complete(!) sleep time, meaning the time between falling in sleep and awakening. And my experience is exactly the same: That GTR3 is pretty perfect when measuring the complete(!) sleep time. But wait: This Huawei Band 7 on the other hand is measured by you as one ot the worst regarding complete(!) sleep time. So far, so good. One could resume, that you should not take this Huawei Band 7, even if you are fine with only the complete sleep time. But now my experience: I wear the Amazfit GTR3 on my left hand and the Huawei Band 7 on my right hand now for a week, and I noticed, that both watches measured always(!) the same (+/- 1min) total sleep time ! How is this possible ? When checking a lot (but not all) of your videos regarding the exact tracking of sleep stages, I noticed, that every(!) watch has some problems, measuring the right stages of sleep. Even the best systems like the Withings Sleep Analyzer lacks a lot of accuracy: None of them tracks sleep stages in a range of 80% or better. Only regarding total (or complete) sleep time, there are a few watches (like the GTR3), which are pretty near (say more than 98%) to the actual complete sleep data, regarding your measurements. So how is it possible, that you measured the Huawei Band 7 different than the Amazfit GTR3, but I noticed, that they track complete(!) sleep exactly the same ? Well - maybe we do have different sleep habbits. And some watches do track well the sleep of one person, but have trouble, tracking the sleep of an other person. My conclusion: Tracking sleep stages is still mostly only a rough estimation, tracking total or complete sleep might be working much better, but even there, the accuracy might be different from person to person.

Amazing review! Huawei watches seem to be quite good on most tasks, but fall short on sleep tracking. I've been wondering if using Sleep for Android app to take advantage of these watch's sensors would make for better sleep tracking, have you ever experimented that app?

Now that is a review. Thanks, doc. I love these kind of reviews, focuses on experimental and data analysis.

Please review amazefit band 7 too please, I am thinking to buy it

I searched for a group of Arab videos that talk about the same topic, and I only found the satisfactory explanation in your videos, 'Thank you for your effort.

please review Amazfit Band 7!

hi Rob, Huawei Band 8 is released with upgraded algorithms TruSleep 3.0 and TruSeen 5.0, can you please test it? that will be great, thanks!

Hey Rob! I was one of your first subscribers :) It's good to see that the channel is growing so much! Wanted to ask: what are the best budget sleep trackers in your opinion? Thanks for the great work!

Just a personal advice. I got the band 6 (maybe it is the same with the band 7). I used it in the pool and it broke, probably one of the connectors with the button. So maybe be careful with that. Thankfully Huawei replaced mine when I took it to their service. There is a video on youtube of a guy that says clicking the button under water damages it (wich is what I did). He also says that his band revived after drying out for a few days (mine did not revived, it got stuck in a reboot loop). But who knows, maybe mine was just a defective device. Other than that it has been a good heart rate sensor and sleep monitor (just for the total sleep time and nap time). Also, thanks Quantified Scientist, you make a great job here, next time I'm definitely buying whatever you recomend.

The best and only useful reviews. Other tech reviewers should be ashamed to be on the same platform as you!

Oh finally the wait is finally over! I was a bit worried last couple of weeks, I was thinking like "What if I buy Huawei Band 6 right now then immediately Huawei Band 7 is released days after I'd be fucked up", and now I have update the wishlist 🤣👌

That was informative. I was researching all over for the sleep tracking accuracy of huawei band 7 and it is off my list now after watching this video. Thanks

That was such a dedicated review breakdown! Thank you for this. It helps us choose the best watch fit to our needs.

Great review. I really like you videos! I think you could more indeep comparison between 6 band and 7 band of Huawei, or against their competitors like Mi band 6. Once again, thank you for the great video.

Hi Rob. Great review as usual. Keep it up! Have you considered reviewing a COROS device? They've just released na interesting update which claims to detect the REM stage and I'm sure we would all love to hear your opinion on that...

Superb video again. Your hard work shows in the detailed analysis. One thing I noticed, the Huawei Band 6 though quite accurate as a step counter seems to have a mind of its own and counts steps even while the person is totally at rest and not even wearing the Band.

Watched this and still bought band 7. I like the quick release straps more in 7 than in band 6

love this guy! Respecting our time and providing value!! Thank you!

wow what an amazing channel - so much detail - well impressed

Man your reviews are spot on. 🎩 off to you sir 👏 🙌

I am curious about the stress measurement. I use this band and whenever I do massage to clients (I'm a massage therapist) my stress level will go high 😂 even though i don't feel stressed at all.

Mine still rocking after 2 years

High quality content and love the comparison graph you included in this video!

I really like the new correlation overview! Makes things way easier to find a accurate watch!

Great review and excellent reviewer, nice job.

Great review. Very comprehensive. I liked the close up photography as well.

Wow, Rob! Your videos are incredible, and so helpful. Thank-you so much. One thing that I find frustrating with this Huawei band is that it does not count side steps or backward and forward motions that are not full steps. For example, when I am working on our canning line, I am constantly side stepping and back stepping. I have done that for hours at a time without the Huawei band logging a single step! It seems a little unfair since I am always getting a workout! My Fitbit always logged those steps. It's a rather big anomaly that I thought you might find interesting for future videos! On the exact same type of work day, the Fitbit would log over 20,000 steps while the Huawei Band 7 will give me 3,700! Why the big difference? I know that the Fitbit tends to give you some free steps, but that discrepancy is crazy. Is it in the type of sensor used?

Gutes video 👍🏼 Wann wirst du das neue Mi Band 7 testen?

Hi, your reviews are amazing and very specific. Thank you for the work you do! I would all like to advise you to add the accuracy of gait tracking when you do sportwatch reviews: it would be interesting to understand, in addition to beats and GPS accuracy, which device is more accurate in recording the average pace (it can be done either cycling or walking while running). Indeed, it seems that the various smartwatches are very different on this point!

Amazing and detailed review. It's a bit disappointing that the Band 7 gets slightly worse accuracy than Band 6, I was looking to upgrade from Honor Band 6. But as you mentioned, both seem to have the same sensors, so maybe it's a matter of software updates and the Band 7 will get better at tracking. Still on the fence whether I should wait for Band 7 or get the Watch Fit as it's even better than Band 6... Though it's more bulky, I love the small form factor of Huawei bands, you don't notice them on your wrist.

Man, you're awesome. Such a great video compared to the rest. Keep it coming 👍

Exactly what I'm looking for. Thank you!

Your review is awesome. Exactly what I was looking for. Thank you.

You are so dedicated to your vids! great video!

Hey Rob! amazing videos!! you are my "go-to guy" when it comes to deciding what to buy! Is possible for you to do a review of HUAWEI WATCH D ?

Thank you very much for the review! I'm in thoughts of buying these watches and was not sure if sleep tracking began to be reliable compared to 4-5 years old models. The testing cleared everything I've been doubting about!👍

I love watching these. Are you going to review the Pixel watch when it comes out?

I am more concerned about overall sleep time rather than sleep stages. How accurate is the band at tracking that?

Huawei Band 8 review would be amazing

Thank you for this! I am thinking about getting this for my mom because ae need to monitor her oxygen levels and you gave me a lot of help in deciding if it is worth it. ☺️

Hi Rob, when will you release your review for the Huawei watch fit 2? Been waiting for your review before i purchase

Good job, but just add RAW EEG spectrogram to somnograms compairing slides (on top of as example)! It will be much more informative and answered to many questions about relevaiting of your compairing.

Amazing reviews mate. Thanks a lot for your work, it's extremely helpful.

Hi! Have you ever considered testing the Fossil Hybrid HR? It's an interesting hybrid watch using e-ink, claiming to have a 25-day battery life while also having fitness features. However, I'm not too sure about the accuracy. Appreciate it!

So helpful! Thank you very much for this very insightful review!

Hello many thanks to have spent time for show all that , here are datas very interesting... you're the best , please continue like that . good job thanks.

I am quite happy with the Huawei Band 6 I bought in March 2022, your review help me decide... that and also a great deal at 30€. I did not get it for the sleep tracking so the under performance do not bother me much, that mentioned not being able to set up the sleep time range is bad and if you are working on a night shift the band is 100% useless as the sleep time is considered as naps and you do not have any details. But again for what I got it (steps, some activities, heart rate etc...) I am ok and will not upgrade to the 7, maybe to the Watch Fit but I like a small wearable device as I am always wearing an automatic watch and will never stop. Also as an iOS device user, I have to say that you do not get the SMS and that's a shame.

Are the straps for band 6 and 7 the same? Awsome review! I always watch your review before considering any smartband / smartwatch change :)

Always on time for reviews

thank you for uploading this video i was looking to purchase this band and i love the red colour

Great review! Can't wait for Mi Band 7 to be tested

Time to review huawei band 8

Thank you for the great review!!! Now i know that i can ignore all the sleep stage data! There is also something called "Breathing Quality" (under sleep section) and stress scores in the HUAWEI Health app I wonder if they are accurate.

woo man, this review deserves to be shown on TV

Very comprehensive review. Well done

I had decided to buy this Huawei Band 7 but I reminded something decisive to me. Spo2, heart rate, step count and other details are pretty important to me, but what about stress sensor? I mean, Huawei Band 7 has it? Have you checked it out on another video? It'd be pretty nice if you had it 🙏🏽✨ Really pretty thanks for these videos. I was going to buy Xiaomi Mi Band 7 but I saw Huaweis better (for my necessities). You are the best dude. 🙏🏽

Hey, love you job! When you will do a review of Xiaomi mi Band 7?

Love your stuff, Can we get an update on the accuracy of the device after updates, and the same with the mi band. Thanks 🤘

Hello! I really like your channel. The analyzes are very interesting and useful. I would like to know how to export data from huawei band. Can you tell me? Thanks!!

Superb channel. Keep it up brother!

I love your reviews. Why don't you do calories measurements. Because I have bought this band 7 and the calories counter is so ridiculously low. I'm disappointed

Fantastic e real review!! Thanks

Thank you very much for the information, you are so cool! I'm choosing between huawei 7 and xiaomi 7 pro, but can't find information about this xiaomi product.

Amezed by your review! One more subscriber!

can you do a review of the huawei band 8?

Could u please review smartwatches in a video which have better heart rate monitor and are in the range of less than 60$

nice intentive review very helpful. thank you very much

Mr Rob, for the casual ("poor") athlete, best sportwatch with GPS: Huawei GT 2e (TruSeen 3.5) x Huawei Band 7 (TruSeen 4.0) x Huawei Band 4 Pro (TruSeen 3.5)?

Hi! I'm from Brazil and I just discovered your channel, I understand a little of what you say through the translated comments to get an idea which one is better in your comparisons.... my 2 doubts are the following: 1* which is the best smart band or smartwatch to monitor sleep up to about 105 dollars? 2* which is the best up to about 55 dollars? If you can answer me I would be very grateful for the help, because I want a smartwatch / smartband to monitor my sleep around these values.... You just got my like and another subscriber to your channel.

very comprehensive video as always!

It cost me 30 dollars to buy a band 7 meanwhile samsung watch 5 costs about 260 dollars. And i heard that samsung watch 5 has the same sensors as before so its a no brainer to get the band 7.

Exactly at which point of the left arm did you wear the watch? 2/1 finger of distance from the wrist?

Bro iam from india and i thought to bought a smartwatch/band and did some research and i found your channel it was a gem. Initially i thought i would go for amazfit bip u pro and see your review and decided to bought haewaii band 6 or mi band 6.your suggestion needed. I only want some decent tracking on skipping exercise. Will you please suggest me and what about some indian brands(boat,noise,real me etc) it will increase your view count as well. Thank you for all your reviews.

Hello.... excellent video, always very useful.... please do the analysis of the new Garmin forerunner 255 series... I want to buy it but not without seeing your analysis.... please, greetings and thank you very much. ...

I think the Huawei Band 6 really set the bar very high for the competition at its price range

Great video! Wait for huawei fit2👍

Please test the new Mi band 7 and Amazfit T-Rex 2

Damn this is like a presentation of a bachelor thesis 😂 I am interested in this watch, now I am very well informed. Thank you!

Wow! The best review!

Man I'm done buying a health tracker but still watching these for the anxiety and depression curing wholesomeness of your videos.

Hi, I just want to say i love you videos and all the effort you you put into them!!💕 I was wondering if you can review the Xiaomi watch S1 or the I was wondering if you can review the Xiaomi watch S1 active, because I really like the looks of it, but I dont know if the watch is accuracy, so can you please review the watch!!🙏🏼🙏🏼

Thank you so much for the research and excellent presentation for each video. They are so clear, data-driven and well-planned. Was wondering which sleep tracker to get for some time and the graph you plotted at 21.15 made my decision so much easier. Bought it using your affiliate link as a tiny tiny gesture of gratitude. Cheers! :)

Great detailed review 👌🏾👌🏾
