Could you please review the Fitbit sense 2 once again. Since charge 6 has improved a lot after updates we want to know if sense 2 has improved. Please review it once I'm rooting for the device since it's matching my exact requirements.

[@Gamerglotzer]

Apple should give this man early access!

[@brinckau]

Yes, I can't believe they are ignoring him. It's like they don't care about getting reviews that show that their devices are very accurate.

[@johnsuckher3037]

​@@brinckau it's a risk as well. He won't silence bad measurements if they ever mess up. There are bigger names that gladly just show shines and rainbows

[@marioko123]

Excellent review. I would also like to see the sleep test. Series 10 has an FDA approved sleep apnea detection, so I think it's going to help with the sleep stages.

Your thorough analysis convinced me to switch from Samsung to Apple about a year ago and I really don't regret this decision. I watch the channel with great interest. Fantastic work, thank you!

The only review that i was expecting. Thank you!!

[@TheQuantifiedScientist]

Thanks so much!

[@cunningham.s_law]

you should show how two chest straps correlate as a reference

[@washedtoohot]

I like that! It would be cool if the Quantified Scientist would also teach us some data analysis techniques :)

[@roadrash999]

He has done that on chest/arm strap reviews.

[@Gengh13]

Already done in a previous video.

[@TheQuantifiedScientist]

I did it a long time ago, but I will redo it at some point. I will first do Garmin vs Polar chest strap and then potentially Garmin vs Garmin and Polar vs Polar :-). Downside is that one chest strap will always be suboptimally places

[@cunningham.s_law]

@@TheQuantifiedScientist if you figure out what the baseline noise is for the same sensor then you can add some error bars on your lines

[@scoti5]

The correlation for everything other than the weight lifting is nothing but amazing. Looking forward to the full analysis to see how it affects the results!

[@KiDNEY5]

Could you please review the Huawei D2? Including the blood pressure feature

[@Muzaini42]

Hi Rob, I just wanted to express how grateful we are to have you thoroughly testing those smartwatches and helping us make the right purchasing decisions. I also wanted to check whether Garmin has sent you the Fenix 8 and if we can expect a review video for it. Thanks

[@JakobDam]

Thanks for making these - you’re the golden standard for smart watch reviews!

[@LordYabagucci]

Waiting for your Garmin Fenix 8 full review video to make my next purchase! Hoping for a huge improvement 😄

[@r.corman0209]

currently own a series 10 46mm for about 2 weeks now. Upgraded from series 7. Biggest difference I can see in heart rate tracking is that the series 10 takes some time to lock in on the heart rate. sometimes 1-4 minutes in the beginning of any workout. Which is very annoying. And from your charts it looks like you had the same experience. In your chart one can see that the Polar H10 starts heart rate tracking immediately. But the apple watch value starts some time after the H10 has locked in. Especially in your running test. I also own a H10 and was hoping not have to use it with my new watch. But I'd rather not go up to 4 min in the beginning of a workout with no heart rate data.

[@amromohammed193]

Could you do a review on the new Mi band 9, wondering if it improved over the bad performance of mi band 8

[@deivytrajan]

You’re the only one who actually test products. There is a common misconception that Garmin are the best for sport tracking or sleep tracking, turns out apple is unbeatable in that lmao. Thank you, you made me buy apple watch

[@robertjleter]

Please test the Huawei D2 and their health functions(blood pressure)

[@geraizgermanii]

Bump

[@x0x0xxxx68]

What I wish for is a Garmin Fenix as it is, but with the sensor accuracy of apple.

[@julian-jh8mp]

same. man, same...

[@mortenvinther8940]

You havent checked out desfit or dcrainmakers test of the Fenix 8 or do you only trust one guy results? Its literally as accurate as this for running and cycling..

[@rizmo.]

same bro.. switched from an AW9 to a Forerunner 955. The FR thinks I'm asleep 99% of the time and my awake phases are measured as REM. :( That's the only downside to that switch.

[@x0x0xxxx68]

@@rizmo. never considered an Apple Watch in the frist place because... 1) i am spending way too much time on my smarphone. I dont need another one on my wrist. Sport and health features is most I want. Payment, music control and optianal call control are nice as well but I really don't want more. 2) one day of battery time isn't of taste. I really don't like having another rechargeable gimmick that needa attention once per day. My Fenix 7X needa to be recharged every 3-4 weeks. Just perfect.

[@florinRinRin]

I agree, it would be a killer. Not sure why the focus on the sensors isn’t there for Garmin 😢

[@MusicForHourss]

Maybe the different wristbands make a difference? Tightness and such

[@paladinsrage4646]

Please compare the new oura ring to the last gen, and possibly to any competitors! 🙏

[@susieyx]

Very curious to know how heart rate correlates to different tightness of the watch band! Does a tighter fit mean more accurate readings?

[@montalbano1972]

missing spo2 test, was very useful and sleep test. Thanks great job

[@MisterWalter864]

There are medically validated devices that test spo2 and instead Rob using them he created a whole pseudo-scientific approach. His sleep stuff is spot on but his spo2 was no far from that.

[@nicktheneko]

Could you please make a heads to heads comparison between the Samsung Galaxy watch 6 classic and Samsung Galaxy watch 7 because in your videos you used 2 different ways of measuring and testing the 2 watches so it's hard for me to decide which is the better one

[@tomwoodall1463]

Apply is going to need to get the o2 sensor patent stuff figured out before i buy another Apple Watch

[@saysoco]

wow i'm so grateful to find you and your best-on-KZbin thorough scientific reviews. i have an Apple Watch 10 but was considering buying a COROS (Pace 3) because i assumed their arm HR monitor would be more accurate than the Apple Watch (on the wrist). so i was shocked to see Apple at the top of the HR accuracy charts and you've saved me quite a few hundred dollars too...

[@Martin-q6w5q]

Thank you sir. The only scientific review of smartwatches I can find!

Another awesome video. Nice change in style. Little less workmanlike and more personal edge. Love it! Nice work man 🤟

[@pi3ni0]

Now, let's see the sleep score! :)

[@MisterWalter864]

it has been weeks!

[@radustegarescu4872]

Good job! But from my experience with apple watch (series 6 and my wife's series 6 & 7) I found that it really struggles to pick up the heart rate during outdoor running, especially when it's colder outside. I constantly had to move it, to rearrange it in order for it to get some reading, otherwise it would gray out the heart rate and show absurd values. My wife even changed the watch, from 6 to 7, and it had exactly the same problems. When I tried to find some info about this on the internet, it seems quite a common problem, so I doubt the accuracy of the Apple watch corresponds to that of the Polar H10. Also Garmin has the same problems when it's cold outside...

which is better for sleep tracking, se 2022 or series 10. not sure if series 10 uses body temp sensing for sleep track or does the 4 core processor increases the accuracy of the result. please assist

[@EduardoHenrique-nd1ro]

Amazing video! Thanks for sharing! Cheers from Brazil!

[@DmitriiKorsun]

Hi Rob! Please add physical exercises such as push-ups and pull-ups to the test. The thing is that at such a load the muscles of hands and forearms are strongly strained and as it seems to me blood flow in the wrist capillaries can be blocked for a moment, which affects the measured pulse rate. At least when I do pull-ups, no device with an optical sensor (Garmin Fenix 6, Amazfit GTR) shows the correct data. I'm even thinking of buying a chest sensor like yours.

[@RYO-dy8rk]

Hey mate how is the accuracy of the Apple Watch temperature sensor?

[@davidstrohmaier]

Great video. I always watch your videos before I make my mind on my purchases. Could you please tell me when will you release the sleep tracking analysis that you usually do?

[@ShanSundars]

Excellent analysis as always. Keep helping consumers make informed purchase decisions. Please do make a video of your "Top 3" watches for both iOS & Android worlds by end of the year. Would help a huge lot of people including me.

[@srijasty]

I’m experiencing an issue with the Apple Watch 10 where the heart rate sensor is not working correctly. I’ve had the same problem with the Apple Watch 7, and even after three series of watches, the issue persists.

[@srengramegeberg8347]

Sawpped from an Ultra 1 to the S10. Titanium for the durability. Loved my ultra as it was the first Apple Watch I've had that didn't scratch. So for me extra durability is worth the cost, as eSIM is a must for me. I absolutely love the slimmer fit of the S10. Made me realise that I'm not really into big watches. Whether I charge every day or every 2 days matters less than I thought. It's all about the habit, and adjusting it to every day. I am also a big fan of the rounder screen, it just makes the different watch faces look so much better.

[@dopesec]

Great review!! mi band 9 🙏

[@JigsPega]

Great review! Thinking if the apple watch series 8/9 could have the same results data if they are measured at the same time series 10 is measured. The previous generations had software updates. Maybe they would have the same correlation values. This could be an idea, like you can compare the current release to the previous releases of the watch.

[@HenPapirman]

Just wish someone from Samsung watches your videos and learn from them. Take Apple watch, dissect it, reverse engineer it. 3 years I've been waiting for a good Samsung watch to be able to track HR and sleep as accurate as Apple, if not better. Not only sports HR but regular good HR, and BP and all that jazz.

[@GadgetyMV]

I agree! Whether or not Samsung will may come down to company culture and the resources allocated to product development. Otherwise Samsung's performance would have leaped with the recently launched biosensor upgrade, but it didn't.

[@BWV478]

That would be illegal.

[@florinRinRin]

Also from Garmin 😢

[@sudhanchhetri1267]

The worst thing is people using Samsung watch for heart rate and sleep tracking are actually getting false informations. 😂. For such matters, it’s better to use the accurate one or not use at all. I think samsung won’t be able to beat Apple or even Huawei or pixel on this one.

[@HenPapirman]

@Petrvsco I've been with Samsung since the first Galaxy s1. I was the one who installed roms and designed and animated their login animation (those were the days). I love Samsung's design, I actually love Samsung. I can't stand Apple's phones. Samsung is what I want, which is why I shall not buy their watch until they get their game together.

[@nathaniellecompte55]

Can you re-review the garmin instinct 2 with the newest firmware?

[@przemysawkaczmarczyk477]

Hi. Could you explain me one thing? I'm wondering how it is possible from the technical point of view that for example Garmin 165 has correlation 0,935 in indoor cycling, 0,975 in outdoor running and only 0,65 in outdoor cycling where outdoor cycling is the result (or at least it should be) of mentioned two activities. It's the same with Coros Pace 3.

[@heenriik]

Is there a different heart rate sensor in the older Apple watches?

[@silviacoppi7442]

Hello Rob, thank you for your tests, I appreciate the possibility to compare the different watches since the tests are the same. Just a question, is your intention to comoare even the hrv values? I’m sure you already know the relevance of this value and it would be great to have this value to compare within different watches. Thank you!

[@BigBananaDaddy]

I was so eagerly waiting for this dude to upload ❤❤❤ 😅

[@ketle369]

When people are complaining about 1-2 heart beats being missed it’s really not an issue. It’s way within the margin of error of any device. People still try to tell me that a heart rate chest band is more accurate, but in real life working out, jogging and cycling I really can’t tell the difference between my wahoo heart rate monitor measurements and the Apple Watch. I even tried several times running both devices wahoo and Apple Watch while cycling. There’s no difference. I prefer using the Apple Watch as I find chest straps more uncomfortable.
