[This review was collected as part of a promotion.] I got my Ultrahuman ring a year ago! Overall, I love it and have recommended it to multiple friends and even got my husband one. I love how there's always new features being added, like the cycle tracking. Only bummer is the gold exterior has faded on the edges, but happy with the UX and functionality of the app and its features.

[This review was collected as part of a promotion.] I bought my ring 13 Month ago, and sadly the first versions I received had some problems. On the first one after 2 Month all sensors stopped working but Ring was still charged. On the second and the third ring the epoxy got weak after 4 Month and pieces of epoxy fell out where upon the ring either stopped working fully or took a day to charge and half an hour to discharge. The forth ring I received now 3 Month ago and sofar so good, Epoxy still normal, sensors work fine and battery all ok. All broken rings replaced under warranty without discussion. As for its functions, it is just great, I use it the most to track my sleep and heartrate, but also tracking sports is easy. What I like the most is that you do not notice wearing it, due to its weight, same or lighter then other "normal" rings.

The Ultrahuman Ring Air stands out for its lightweight, comfortable design (It is barely noticeable), and super-long battery life. I love the Gold finish!! It monitors my sleep. I keep it in Turbo mode, which tracks the maximum amount of data, and still averages more than six days per charge.

[This review was collected as part of a promotion.] Able to reorient my routines based on various parameters in order to achieve max scores on all. This helps me getting the Ultra age and cardio age as closer as possible to my actual age. Trying hard to get those age numbers below the actual ones.

[This review was collected as part of a promotion.] I have had the ring since November 2024. The hardware seems solid! The app has improved over time, but I do feel like the data should give more actionable insights rather than being so broadly informative.
