    Best.gift.ever. Battery lasts a long time. After four days it’s still at 50%. I’m tracking my sleep and trying to improve. Now that I have this ring, I understand my sleep patterns and have suggestions on how to improve. Looking forward to more health data in the future.

    I like my Oura ring but I feel it isn’t as easy to keep it looking nice as I would like. It shows wear easily. I know I can buy a ring cover but I returned one (diff vendor) because it was so bulky. The app isn’t as user friendly as I would like too—it’s not easy to look at past data on the app.

    My wife and i both bought one. It gives a lot of information and metrics. If you act on the information then it seems to be beneficial. I have improved my heart age by half a year already. It is noticeable with some activities like driving.
