I bought this a while back, and at first, it worked well. However, I realized the battery doesn't actually last the whole week, just 3-4 days maximum, and I charge it overnight. The ring also randomly disconnects or says there is not enough data to give me my sleep records, for example, which is weird when I know for a fact I slept 6 hours.

[This review was collected as part of a promotion.] Overall, really happy with the superhuman ring. I like all of the things that tracks. If I was being critical, I think that the walking step count can be inaccurate at times especially when driving in the car with bumps it will still record steps so by the end of a very long drive you can have over 10,000 steps recorded Other than that’s great

[This review was collected as part of a promotion.] I bought this ring 2 months ago and had issues the first weeks as its sleep readings differed greatly from my fitbit- which I also wear to sleep. After several weeks tho, the difference between the 2 wearables are not that big so I guess it has calibrated tho there are still days that it seems off.

[This review was collected as part of a promotion.] I have had my ring for 3 months so I feel like I’ve had plenty of time to really utilize its features. I love the sleep data and feedback. I have actually been able to make positive changes to improve my sleep behaviors. I’m also very motivated by my step tracking, and heart health results to move more! Overall, I’m very happy with this investment in my health.

[This review was collected as part of a promotion.] The product performs very well with regards both the tracking of the health data and also the battery lasts around 4 days with full scale continuous monitoring. Easiest how to take care of the battery is to charge during the dinner or when going to shower. The shiny version

[This review was collected as part of a promotion.] Have been using the ring for more than a month now, and what blows me away the most is the accuracy of the insights. Sleep tracking is the feature I like and use the most, and the ring being very comfortable to wear to bed is what helps. There is no manual input needed post initial setup, just wear it and consume the insights. This is the best tech purchase I’d made in the last couple of years.

[This review was collected as part of a promotion.] I love the data the ring provides! It has been really interesting seeing what affects my sleep and hoe I can make improvements to help shape how I feel throughout the day. My only negative is how long it takes to charge. I want to wear it at all times to get the data. It would be nice if it could be fully charged in 30 mins so I don’t have to have it off for so long. Overall an amazing product!

[This review was collected as part of a promotion.] I am really enjoying my Ultrahuman ring! I love seeing my sleep score when I wake up and tracking my stats throughout the day. It has really helped my daily and sleep routine to become more productive. I really appreciate that Ultrahuman is always adding new features, insights, and small little changes that help the overall function of the ring. The only thing I wish was an option, was to sync my apple health data to my ring as well, instead of just syncing my ring data to my apple health as this sometimes leads to double counting of steps, etc.

[This review was collected as part of a promotion.] I am very happy with the app, the comfortably and easy usage of the ring. Also I like the ongoing improvements and additions. The only improvement I have is that once my ring was broken, it took quite a while to get an replacement because I had to do several firmware updates before it was agreed to get a replacement. The support was always super quick and helpful but this I found a bit dissapointing.

[This review was collected as part of a promotion.] I have had the ring for a few months now. To be honest it came defective and I had a hard time having it replaced.. it took almost two months to have it replaced. That being said it seems to work well. There is a lot of information tracked so it is difficult to know how accurate it really is. The sleep tracking and temperature tracking work well.
