[This review was collected as part of a promotion.] I’ve had my ring for almost a year now and I love it. Tracks everything without the need for monthly subscriptions. Ring is very aesthetically pleasing and not bulky.

[This review was collected as part of a promotion.] I bought this about 6 months ago and it has been great! I wish there was a feature to add extra sleep (sometimes it thinks I fall asleep later than I do) and it will affect my sleep score.

[This review was collected as part of a promotion.] There are so many features I don't know exactly what to do with them all! I love this for the sleep insight and the caffeine window.

[This review was collected as part of a promotion.] I’ve used both oura and Ultrahuman. The air is absolutely light and sturdy. I use it for my weight training and able to resist the scratches!

[This review was collected as part of a promotion.] Received as a Christmas gift last year and have worn it everyday since. Love how much info it gives me on my health.

[This review was collected as part of a promotion.] We’ve had the ring for a little over 3 months. The ring has helped, by following the caffeine window my headaches are less frequent.

[This review was collected as part of a promotion.] I changed from Oura to Ultrahuman, as I did not want to pay a monthly subscription fee. I like it better, and find the feedback on sleep, sleep debt and circadian rhythm information motiviating.

[This review was collected as part of a promotion.] I’ve had my ring for about 2 months now and I love it. It’s super convenient. I love that it tells me my caffeine window which is very helpful with my work schedule.

[This review was collected as part of a promotion.] Bought this ring last summer and I have been thoroughly enjoying it. I love the insights I'm getting and the ability to set tangible goals.

[This review was collected as part of a promotion.] I bought this several months ago and it's amazing. I also work night shift and it's able to accommodate to that.
