    Perfect! :) I love my oura ring. Oura is very accurate and can detect all the changes that I also feel in my body, but did not know how to react to them before. I love the data that I get about my sleeping and overall readiness. I love how accurate it is to predict my periods, when I should take it more easy and when I can give it a go. I would recommend it to everyone who wants to take good care about their health.

    Love this ring! I have sleep apnea and wanted to track my sleep. I have apple and garmin watches but don't want to wear to bed. This ring and app tracks a lots of biometrics. It gives me ratings on stress and my bodies recovery. My activity levels and detailed sleep pattern to the minute. The stealth ring for men is durable, however, does have propensity to scratch. Recommend the latex protection covers on Amazon for wearing for golf, yard work, etc to protect ring.

    This is my first Aura ring. I’ve been wearing it for about 3 weeks now and so far I have been very happy with the accuracy of it and the information it provides me on what stressors my body is under. The only reason I gave it a 4 instead of a 5 is because it scratches so easily. I spent extra to get rose gold since it’s something I would be wearing all the time. It’s a beautiful ring but I’m not sure in a year what it will look like if it’s this scratched in just 3 weeks.

    My wife wanted one of these because she doesn't always remember to wear her smart watch. I was hesitant at first, but after getting it, I can say it does and tracks so much more then the watch does. From sleep patterns to heart rate, this was well worth it and she loves it. One thing to note is that it does have a yearly subscription for all the features so something to keep in mind before purchase.

    I have really enjoyed my Oura ring! All of the features on the app are really awesome and have made me a lot more conscious about my sleep schedule, meal schedule, and activity throughout the day! I have had it for about a month and have noticed it already is pretty scratched. The battery life is nice! I usually charge it while I’m doing my night time routine and it’s charged when I’m done!

    I absolutely love my new oura ring. It’s not bulky and it looks like a regular ring. I love how it tracks my steps, sleep and stress. It also has a feature that allows you to track your meals. This ring is definitely a game changer. At first I did a fitting for it to fit on my ring finger but I saw reviews that index finger is better. And I agree!!!
