[This review was collected as part of a promotion.] I love my ring. It took a little to get adjusted to it and now I feel naked if I leave the house without it. The tracking is interesting and a lot more accurate than my apple watch of Fitbit ever was. I love that I am getting more in tune with how my body reacts to certain things like sleep deprivation, eating later meals and proper recovery from stress, stimulants, working out and lack of sleep.

[This review was collected as part of a promotion.] I bought this a few months ago and I love it so far. It's much less bulky than other workout/sleep/lifestyle smart trackers and I feel that the insights are helpful in detecting where I can improve my sleep and exercise habits.

[This review was collected as part of a promotion.] Up until today, I would have given a 5 star. However, my ring quit working today… I went thru all of the steps to “fix” it, & now I am in a “battery drain” that will take FOUR days. Frustrating!! I’ve only had the ring since March. I’ve had my Apple Watch for years with no issues!!! I hope the “drain” fixes the issue, but for someone who checks my data daily, I’m going to be lost without it.

[This review was collected as part of a promotion.] The Ultrahuman ring has changed my life. TRULY! My sleep has never been better. Being able to track my metrics and see my stats in real time has been a huge blessing. There are so many more benefits included. I truly don’t know how I lived without it before. Would recommend to anyone and everyone!

[This review was collected as part of a promotion.] I bought this a few months ago to tell how my sleep was going because it felt like I was asleep a lot but waking up not fully awake. It was great to see when I’m in deep sleep and or not getting much sleep at all. Even seeing recommendation on when to stop eating or getting the most out of the sun had been a great add to what it does. Want to learn more about the ring wish it came with videos on what to expect.

[This review was collected as part of a promotion.] The Ultrahuman Air has been such a game changer in my life! It's made my health feel less like a guessing game and more like something I can actually control. Definitely would recommend for anyone who's looking to take their sleep and their health to the next level!

[This review was collected as part of a promotion.] I have had the ring for a few months now. To be honest it came defective and I had a hard time having it replaced.. it took almost two months to have it replaced. That being said it seems to work well. There is a lot of information tracked so it is difficult to know how accurate it really is. The sleep tracking and temperature tracking work well.

[This review was collected as part of a promotion.] I recently switched over from a forever Apple Watch to the Ultrahuman Ring AIR. Instead of establishing unrealistic goals and allowing my watch to control my life, the Ultrahuman ring helps me track my health in a way that is just that - healthy. I like that I can see my caffeine window, stress levels, track my cycle, and monitor my sleep patterns. Also, the ring is so cute and less bulky than a watch!

[This review was collected as part of a promotion.] I am thrilled with my Ultrahuman Air ring. I purchased it and a leading competitor to do a side by side review. After just 2 weeks, I returned the other ring - the Ultrahuman was just so much better. The Ultrahuman app is amazing. Almost immediately I started seeing improvements in my sleep, health and energy level. Both my Ultrahuman app and my Apple Health app showed significant improvement in many areas (HRV, deep sleep, amount of sleep, Vo2, resting heart rate, etc.) in just a few weeks. I did a lot of research before buying. In the past several people have had problems with their ring not recording data. I have not had any problems. But one person said that when you are picking a size it's best to get a ring that is too tight to take off in the morning without using water. I did that and my ring stays in place during the night. If the ring is too loose it will twist around and not be able to record your info. Also, try to pick a size of ring that you can move to other fingers if you lose or gain weight. Finally, the ring is NOT as good in measuring workouts and your steps as the Apple watch. But I have a watch for that. From personal experience the ring is MUCH better at tracking sleep. It often shows more deep sleep than my watch. Also, it tracks the REM and other stages more accurately. Often I wake up suddenly during a dream. The ring shows that I have gone directly from REM to awake. The watch does not show that.
