Hi Rob! Could you make a Video on recommendations for dedicated finger oximeters for spo2 measuring at night in the future? Criteria for comparison could be: - accuracy - stays on at night - comfort / form factor - price - additional features - android / iphone app quality - international availability Thank you so much for the good work! Keep it up!

I sort of agree, but if you have sleep apnea you just need to lose weight quit being so fat. Last time I checked it was like 85% of people who had sleep apnea were obese. I think sleep tracking is one of the most useless things unless you have some kind of mental, psych disorder.

@@greuju It's 70%, not 85%. And if you stop breathing 5+ times/hour when you sleep, you'll probably be tired. News flash - when people are very tired, they eat more and exercise less. For me, it was 50+ times/hour. I lost a lot of weight once it was treated. But I still have sleep apnea, because the structures of the muscles and cranium are major components in sleep apnea severity.

Wow, so cool when someone you watch actually sees your video :-)! I'd love it if your affordable oral Finasteride became available in Europe😊!

I love my Polar Vantage V3 paired with my Polar H10. Perfect eco system. Beautiful watch and great accuracy

Great video! Love to see your emphasis on testing accuracy of these various devices. With the demise of the Dreem 2 headband, have you considered testing the Muse headband?

Something I would love to see on your testing of sports watches: a bit more data on the GPS accuracy. You mainly test speed of signal acquisition, and how close the GPS tracks to to actual routes you take. For me, those don't worry me unless they're dramatically wrong. What I want accurately measured for my running is the correct distance and the correct elevation change. For example, I have two watches I run with all the time: a Huawei Runner GT, and a Suunto Spartan Sport. The Huawei seems to measure those most accurately; I run parkrun every week, on measured 5K courses, and the Huawei is usually very close to it, and the elevation measured matches up pretty well with other people's stats. By contract, the Suunto is usually slightly low on distance (typically about 2%), but the elevation is terribly wrong, typically by 30 to 70%. I believe it's a software issue rather than hardware, but still, it's so tiring correcting the elevation in Strava every time.

Amazing as always, thanks! I was wondering if you were planning a full review of the Pixel Watch 2 😇

I love your videos. On point as always! Have you looked into the Oura's stress tracking? Very curious how effective and accurate it truly is.

00:58 🔥 Eight Sleep Pod 3 is a top pick for sleep quality improvement, offering independent temperature control and precise sleep stage tracking. 05:52 🌟 Aura Ring 3 stands out as a comprehensive sleep tracker with high accuracy in deep sleep detection, though slightly less accurate in REM sleep. 10:46 ⌚ Whoop Strap 4.0 serves as a versatile fitness tracker with decent heart rate accuracy, suitable for various exercises, but doesn't excel in any specific area. 17:57 🛌 Whoop Strap's sleep tracking is good enough for overall sleep stage estimation, but it might overestimate deep sleep and underestimate awake time for some users. 19:04 🏃‍♂ Whoop Strap is recommended as a top choice for health and sports tracking due to its interpretable data. 19:18 🫀 For precise heart rate tracking, using an ECG chest strap like the Polar H10 is suggested, known for its accuracy in identifying heartbeats. 20:15 📊 Signal quality comparisons between Polar H10 and halter ECG showcase Polar H10's superiority during intense exercises like jogging and strength training, maintaining a significantly higher accuracy. 21:49 🩺 When selecting an ECG monitor, opting for a reputable brand that functions independently, like the Polar H10, is beneficial. 22:18 🚴‍♂ Indoor cycling significantly aided in managing chronic pain, with the Tacx Neo2 highlighted as a reliable option. Standing desks and treadmills under desks are also suggested for a more active work environment. 23:31 🏋‍♂ Having weights at home streamlined workouts and saved time compared to gym visits, emphasizing the convenience of home fitness equipment. 23:46 💊 Recommendations for health supplements like Ule, ag1, and protein powder are shared, emphasizing personal use and not being sponsored. 24:15 💊🦱 The presenter candidly discusses using medications for hair loss prevention, stressing the importance of consulting a doctor due to potential side effects.

Hi Rob, an old subscriber here! Fantastic video as always. I have one request; can you please review the Amazfit Band 7? Because I have kept that in my mind. My main focus point is fitness and health data accuracy.

You are goated for these series .. 🐐

Amazing video as always, I wanted to ask you when did you perform the sleep tests for the Oura Ring using all 3 devices.

Can‘t wait for the scanwatch 2 review to be here finally 🎉

Love you videos dude! Out of curiosity - will you be testing any smart scales at some point as I'd really like to know how accurate their metrics are? Cheers

hey man I was just thinking to myself that I hadnt seen one of your videos in quite awhile. so I looked you up and none of your videos showed up in the list? I had to use another device to send my phone a link that wasnt logged into my youtube to be able to find you. youtube had also unsubscribed me from your channel. how bizarre? I subscribed again though dont worry and glad to see you are still doing this.

Hi Rob. Thanks for the very informative reviews. One aspect that I notice is not always prevalent is the feature of detecting AFIB. What would be the best devices to capture good overall meteics but also has the ability to detect AFIB?

Hey I appreciate all of the work you do. I have had chronic insomnia for years, and I was wondering what device you would recommend to most accurately track my awake time? I don't really care about the sleep stages--I mainly care about how much time I am awake. Thanks!

Please test the other smart rings out there: Ringconn, the Vera Ring, Gloring, etc. Thank you for what you do!

I love and greatly appreciate your work! I noticed you don't have a data point on your graph yet for Muse; any plans to review it as a sleep tracker?

I'd be interested in a comparison of how well different devices track heart rate when just doing daily activities around the house. I was told to keep an eye out for a really high sustained hr when not doing anything strenuous. I have a polar variety, but it's so focused on workouts that it's not ideal for my needs. It's a shame because it seemed to be such a good balance of price, comfort, and accuracy. It's also small and not on my wrist which makes it ideal for doing messy things with my hands.

Awesome as usual!

Great reviews and awesome scientific tests. I was wondering have you tested some non popular branded watches? In particular I was looking at the Koalahealth Smart watchs. Seems to have more features than the more popular brands. I know some of the health features are not FDA approved, but my main features will be ECG, SPO2 (on demand), heart rate (continuous), Long battery life (there's no time to charge in the morning and evening with sleep feature), Bluetooth calls all a must have features. GPS is a plus. Currently using the Fitbit sense, but no SPO2 when I need it. I have short of breath sometimes, so it's important. Thank you

Hi Rob, once again a great review, thanks! I've noticed a problem with the Charge 6. Over time, the cover of the sensors becomes cloudy. On two devices, the problem occurred after about two or three weeks. Do you think this affects the quality of the data? I have written to fitbit, but they are only interested in the fact that this is not a reason for a return and I have not received an answer to the actual question despite following up.

Hi Rob, do you have any public data sheet so I can compare them all instead of pausing the video? Thanks

It would be interesting to see other cooking and heating bed options other than eight sleep. Not all do tracking, but they do heating and cooling without the subscription and price.

@@TheQuantifiedScientist I know there's the Chilipad by Sleepme. I've been looking at that one.

This is where I’ve gotten quite confused. I have the 8sleep and also use the Apple Watch Ultra and Whoop and sometimes the Muse S headband. (Yes I play around with a lot of devices and data) I don’t know why but I sometimes get a lot of disagreement between the Ultra and the 8Sleep bed. For example, last night my watch saw no deep sleep at all but the 8sleep saw 1 hour and 11 minutes of deep sleep. Whoop seemed way off with 1hr52 minutes and some of that during the second half of the night. Wish I had a Dreem2 that could easily maintain signal locks.

Are you planning a UltraHuman ring review? I would like to see a comparative video between the UltraHuman and Oura rings, and it would be very helpful. Thank you for everything.

It would be great if you did fitness band reviews. Screenless. I love wearing analog watches and want to wear something to track steps and some fitness info

Props to you for talking about the hair loss. I decided to not fight my dna and just let it go. Its nice to hear experiences from those who take the medicines though to make it less scary for others to consider asking their doctor about.

The sleep data has been fairly different so far. The Apple Watch doesn’t seem to be tracking my deep sleep well. I’m thinking it might not be strapped on tight enough? Either way I was surprised to see the disparity between the two.

Great data. Which wearable, that doesn't require a montly subscription, would you recommend to track oxygen levels?

I'm super curious about the ice ring! The price is really interesting

You included activities as sitting and chores in your polar H10 comparison to ECG. Would you recommend to buy H10 if I want to track my calories during the day? I assume that H10 would be the best for tracking calories. I'm not big fan of watches that's why I'm thinking of H10 so I know my energy expenditure.

I'm in the market for a new wrist HRM, is the graph that can be seen at 15:30 available anywhere in a more easily readable format, such as a table with the best watches at the top?

Please would you test the new Withings ScanWatch 2 or ScanWatch Nova. Really wanna see if the extra sensor has improved it to a good device, as the battery life is the best of all these watches.

Hey Rob! I've been following you for a few months now and would like to give you a big thumbs up for your videos. I'm currently considering buying the Garmin chest strap (HRM Pro Plus) as I have a Garmin watch and can therefore experience the full scope of features.

I used Finasteride for 10 months and developed severe physiological and neurological side-effects that have not subsided after I have stopped taking the medication 15 months ago. This phenomenon is known as "Post-Finasteride Syndrome" and there is a rising number of men affected by it. Why it might be rare, its effects are devastating for the ones affected. I appreciate that you mention that there is potential for side-effects and that you mention for example the Huberman-podcast about hair loss in which also Post-Finasteride Syndrome is mentioned. However, I am quite disappointed that you use your platform for advertizing Finasteride.
