[This review was collected as part of a promotion.] I’ve been using it now for 2 months and am really happy overall with my experience. As a runner, I find all of the cardio age and vo2 max statistics really helpful and it’s been great to see them changing the longer I use the ring. The battery is good, I charge it whilst I’m at my desk every few days or so and it’s relatively fast to charge to full battery. My only reason for not giving it 5 stars is the period tracking. I was under the impression that as it measures your body temperature it would predict cycle outcomes based on this, not just 28 days. As someone with an irregular period, if it is late, the app just says that my period is in an unknown phase. It seems to basically be their own version of an app such as flo. I don’t find it to be any more accurate, despite the body temperature measuring.

[This review was collected as part of a promotion.] I've been really satisfied with the Ultrahuman AIR. It's made a noticeable difference in both my sleep and morning routines. One of the biggest improvements I've seen is how much quicker I fall asleep—something I used to struggle with. The insights provided by the device have been genuinely helpful in understanding and optimizing my habits. I'm also really excited about the new tag system and what it will bring. It looks promising and could add even more depth to the insights and tracking. If I had to point out a downside, it would be that the step count seems to be underestimated compared to other devices I've used. It's a minor issue, but worth noting. Overall, it's been a great addition to my wellness toolkit.

[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.

[This review was collected as part of a promotion.] Overall, I'm very happy with my Ultrahuman Ring AIR. The tracking features are great, the battery life is good, and the app is very user-friendly. My only complaint relates to the fading of the ring over time. I have had my ring for just under 1 year and it has gone from gold to mostly silver due to fading.

[This review was collected as part of a promotion.] I love this ring! One of my favorite features is the caffeine window and the sleep tracking. I’ve always wondered when i should be tapering off caffeine and what time is best to start getting to bed. If you’re looking to better your health habits, you won’t be disappointed.

[This review was collected as part of a promotion.] Been using the Ultrahuman Ring Air for about 4 months. Overall experience is very good, I really enjoy all the detailed info the device collects. Far more detailed, accurate and helpful than any other device like smartwatches. Battery could be better but it’s not terrible. Some features in the app require an app to be running in the background. Smart alarm in my case sometimes isn’t turned on due to app not running in the background. And the majority of time it only triggers with a fallback timing.

[This review was collected as part of a promotion.] I bought this ring to help me better understand my sleep and habits that effect it. With slight adjustments to my routines, I was able to get much better sleep thanks to the ring. On the other hand, the ring came with much more detail about my lifestyle and insight into my health. I am very happy with the purchase!

[This review was collected as part of a promotion.] I bought this three months ago to track my steps and very happy so far. Step tracker is great and better than buying a watch. I find the battery is good and very easy to charge, lasts long and don't take to long to get to full charge. The sleep tracker is interesting with lots of information. There is a lot of information and I do find I skip over as some of it as I don't really understand it. The add ons are a nice touch and very interested what we will see in the future. As I said great step tracker, interesting for sleep, good for stress and like all add-ons

[This review was collected as part of a promotion.] Purchased and used for 8+ months. A great onboarding experience, a sleek ring and a beautiful app with some great sleep and health insights that have positively impacted my lifestyle. Movement insights are decent though still need to be manually tracked. The battery life was good for the first six months but has dropped as of late and now requires more than one full charge per day - which is inevitable but a little earlier than I had expected.

[This review was collected as part of a promotion.] Love my UltraHuman Air ring. Things a love about it is the sleep tracking. Definitely been feeling more energised after going to bed and waking up on time. Also like tracking how my fitness levels are tracking. Would recommend this ring to anyone
