[This review was collected as part of a promotion.] I had purchased it around 5 months back and I have been tracking the sleep patterns and it resulted in prioritising my sleep and understand how important it is to sleep consistently daily at the same time, my sleep quality has improved a lot.

[This review was collected as part of a promotion.] I have been using Ultrahuman ring for a about a year. When I first started, my average sleep score was in the 60s. Now, it’s consistently above 80. This improvement has significantly boosted my energy levels and overall quality of life. This device is designed for long-term impact, not fleeting alerts. It's a quiet, consistent companion that has truly helped my wellness.

[This review was collected as part of a promotion.] I got this about 4 months ago and have loved getting all of the feedback that this ring tracks. It is very insightful and helpful in knowing more about my body and what it responds well to and what it does not. The sleep feature is my favorite by far.

[This review was collected as part of a promotion.] I have been using this Ring since last 8 months, easily the best wearable on the market. It's so lightweight and non intrusive. I have an Apple watch too but I mostly prefer this for sleep tracking any day. The sleep and stress scores are really accurate. Also love the caffeine window feature a lot, really helps me keep my caffeine in check and the app insights have significantly improved my sleep and recovery!

[This review was collected as part of a promotion.] I bought the ring almost two months ago now and really love how it tracks my sleep and helps me understand what triggers a bad night of rest and what I can do throughout the day to improve my energy. I also love the activity tracking aspect, but I which it was more specific on calories after you log a workout.

[This review was collected as part of a promotion.] I've been using the ring air for over a year now and the experience has been nothing short of great! I love the evolution of body metrics and insights, and the interplay of different features interactions to help optimize my sleep and recovery. Highly reccomend!

[This review was collected as part of a promotion.] I bought my ring approx. 2 months ago. Pros: I really like the design, it's pretty nice and comfy. The user interface is good enough, I can find everything I want easily. The extensions aka. powerplugs are great additions, not to mention most of them are free of charge. My favorite is the circadian rythm tracker, and the smart alarm is also very useful. Built-in breathworks are nice, also free. Exercise tracking is I think as good as you can expect from a ring, plus there are lots of built-in training types. Sleep metrics I cannot compare with other devices or measurements, so I have to rely on what I see in the app, but I feel like they are rather accurate, at least the quantities for sure. Cons: I really wanted to like this ring and I am liking it, but I have to be honest: sadly I'm currently waiting on my third replacement ring. The first stopped charging after a few weeks, the second had a similar problem, but then after a day of trying it did charge up, but then the sleep metrics were gone. The latter was probably a software issue since the metrics during a breathwork session worked, and the sensor diagnosis stated that everything is fine. Regardless of what the actual problem was, it couldn't be used like that. Both lasted for a month, roughly. I only can hope that I will be luckier with the third. If it is really just about luck..

[This review was collected as part of a promotion.] I love my Ultrahuman Ring Air. It provides me with great insight on a lot of health data. It also tells me how to improve my scores when they are not the best. One of my favorite things about the ring is my sleep score and how that affects my caffeine window.

[This review was collected as part of a promotion.] Battery degrades prematurely. I bought hardly used second hand ring air and was offered to purchase ultrahumanX extended warranty through the app. Turns out ultrahuman warranty is non-transferable. As a customer I feel like this company does not stand behind their product and I would never buy their product. There are other well know smart ring companies that has transferrable warranty and stand behind their product.

[This review was collected as part of a promotion.] i got the ring in april & i mainly got it to try to conceive but all the other features are AMAZING!! i love the sleep tracking & it’s on the money with tracking my cycle. the only thing that i feel isn’t the most accurate is the step counting, i always feel like i do way more but i will look half through my day at work (as a medical assistant) there’s barely 1,500 steps by my lunch so if you’re looking for that aspect i think a fitbit or apple watch may be better. the sleekness of it being a ring was the other reason to get it. i’ve also started to notice some inconsistencies with the battery life & sometimes it will drain very quickly other times it will take like a week and a half or it takes forever to charge. i cant judge it too hard though because the health rings are new technology so i am so sure it will only get better!
