[This review was collected as part of a promotion.] I bought this 3 months ago, I was really happy with the device and the software, and happy to see you're pushing updates very often with new feature. But the ring doesn't work anymore since a week ago. The battery runs out after a few hours, even after charging it completely. Something has somehow... changed, and it doesn't work as it should anymore. I've updated the firmware, and run diagnostics, but nothing fix the issue. Which im quite disappointed now, I can not use it and I have no data about myself since the issue started. I have a ultramarathon this weekend and won't be able to use it.

The ring has been outstanding. I use it to monitor my sleep, sleep debt, dynamic recovery, and various other features. The ring's durability has been excellent so far. I have the matte black version. I engage in normal daily activities like washing my hands and doing dishes, and there are zero scratches so far. The battery life has also been impressive. I appreciate that I do not have to pay a monthly subscription.

[This review was collected as part of a promotion.] I bought this ring when I was looking for a smart ring to detect my activity especially my sleep and also my fitness. From some brands, I totally like this ultrahuman. Battery life is not the best but still enough to last for minimum 5 days. A bit expensive though but compared to the accuracy data it gives, it still worth it.

[This review was collected as part of a promotion.] I have loved my ring since I purchased a few months ago. The battery lasts awhile after being fully charged. I love the health insights it gives me and truly makes me more conscious of health choices, for example my step count and sleep health. It gives recommendations to improve certain health insights that are actually helpful. I would recommend this ring,

[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 bought this a few months ago to monitor my sleep since I wasn’t sleeping well, and I loved the caffeine window feature because I was drinking too much coffee—sometimes to the point of feeling heart palpitations. In fact, there are many more functions that help me in my daily life, and I have no regrets. I love it! Plus, it looks great when worn. Thank you, Ultrahuman

[This review was collected as part of a promotion.] We purchased this as a couple a few months back. At first it was doing well, battery was on point and all my stats were tracked properly. Then around July, the battery started draining like crazy. In less than 6 hrs, my fully charged ring was already at 30%. Charging the ring also took longer even if I used the proprietary cable. I started doing the troubleshooting and indeed it also noticed that the battery is draining longer than expected. However, it is not able to troubleshoot properly as I could not wear it for a long time. I hope that there is still some way to fix this or replace the unit. I very much enjoy wearing a ring to track my health vs a watch. I can add the screenshot of the app with the info but I cannot upload images here. Please send me the email so I can send them for your feedback. Thank you

[This review was collected as part of a promotion.] Absolutely thrilled with this purchase! Comfortable lightweight, and provides all the information I need to keep my marathon training on track. I really love the detailed cardio and sleep pattern information which makes it easy to make sure that I am not over training.

[This review was collected as part of a promotion.] I have had this ring about four months now and it has been the greatest! Charge last a couple of days and it is always giving me accurate information! It has been a game changer for my health issues with my doctors as well. I can share the information with them very easy!

[This review was collected as part of a promotion.] I love it! If you’re looking for something that compares to the Ulta Ring (it won’t be named!) then you’re in the right spot. They offer more frequent updates and I personally think the design is simpler, lighter, and more discreet. Although I am no influencer, I continue to recommend this to my friends and family as often as I can!
