Ultrahuman Ring Air Sizing Kit - Black (UHRA-SSK) is rated 4.5 out of 5 by 1155.
Rated 1 out of 5 by from Was great until battery issue after only 3 months [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.

Rated 5 out of 5 by from The Best Health Monitoring Tool [This review was collected as part of a promotion.] I am so happy to have this ring. The complete insight it provides into sleep details has been incredibly helpful and has allowed me to improve my sleep quality. The app interface is also very user-friendly, and all the data and details it provides are extremely helpful. While I am very satisfied with the core functionality, I have a few suggestions that I believe would make the experience even better. I would love to see a more proper step count feature, as well as the addition of GPS data to accurately record the location of my activities. An NFC function would also be a great addition.

Rated 5 out of 5 by from Fitness ring helping individuals improve! [This review was collected as part of a promotion.] I was curious to see how this ring would stack up after using apps to track my steps and fitness. To start, I received a fitting kit to ensure that my finger was the right size, which prevented any discomfort, and the ring appears to be well-made and water-resistant (based on showers and a month of use). The most helpful feature of the ring, which tracks my sleep and active hours, is the recommended caffeine windows and dosage to avoid disrupting my sleep. It also has a lot of other features, such as resting heart rate, and I would suggest this product to anyone who enjoys being active.

Rated 5 out of 5 by from Don’t want to be without my ring [This review was collected as part of a promotion.] The ring has set me on a journey to better understand how sleep affects my health. I’ve received insights I did not know about. I have been able to see how certain behaviors, like late meals, stress, or room temperature affect my sleep. The ring is also very comfortable. I hardly feel it on. The battery life is very good. I charge it about once a week. I bought the silver color. Been wearing it for about a month and don’t have any scratches on it. Overall, I’d recommend this to anyone who wants to improve their health. The key is to stay disciplined and consistent with insights and tips.

Rated 5 out of 5 by from Best to stay fit In stress driven era [This review was collected as part of a promotion.] Earlier I was using Apple Watch which was cumbersome to wear at all time especially during sleep and charging daily was an issue .Since I have started using Ultrahuman I am happily tracking my daily activities especially sleep and calories with a good battery life.the best feature is the alarm clock which will wake you up according to your REM sleep which will make you feel fresh on getting up. It correctly calculated my sleep deficits,sun exposure,heart rate variability and dynamic recovery .. all of which is required to be monitored to stay fit in this stress driven world .Ultrahuman is amazing

Rated 4 out of 5 by from Great metrics but the battery is not the best [This review was collected as part of a promotion.] I bought the ring approximately 6 months ago. Unfortunately after 2 months it died and I was n out able to connect it anymore. Thank to the support we solved everything and I got a new ring in two weeks. Since than I have experienced no issues. I would say in general only positive things about it when it comes to tracking. I really like how the ring measures my sleep efficiency and that for every metric it gives actual explanation what it means and how to improve it. Also things such as dynamic is crucial for me as for an athlete. The battery is not the best but in chill mode it is ok

Rated 4 out of 5 by from Reliable Health Insights [This review was collected as part of a promotion.] I recently purchased the Ultrahuman Ring, and it's been an incredible addition to my wellness routine. During my recent international travel, the ring proved especially valuable it helped me accurately track my movement, recovery, and sleep across time zones. The insights were not only precise but actionable, allowing me to stay on top of jet lag and make smarter choices throughout my trip. The build quality is excellent, and the app interface is intuitive and well designed. Overall, it's a powerful tool for anyone serious about optimizing health and performance on the go or at home.

Rated 4 out of 5 by from Good ring [This review was collected as part of a promotion.] The ring is good. My sleep has gotten a lot better and waking up feels like s breeze with the smart alarm, even with little sleep. The other features are nice too, however I feel like some are not extremely accurate for example, the moving score tends to be really low for me sometimes right after waking up because the ring registers moving during my sleep as steps. On the other side the temperature and readiness score tend to be very accurate, they were able to predict sickness and other low-energy days. The ring scratches pretty easily but I dont mind too much as it is common with my other rings too.
