    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!

    The best to track sleep, heart rate and any health. Way more accurate than any of the other health tracking devices. Love how long it could go without charging for days.

    Great ring. Is not heavy at all and doesn’t look bulky in your hand. The oura app give all kind of good data about your sleep, heartbeat rate and temperature to keep you healthy. It does charge you 6 dlls for the app subscription but totally worth it. It does scratch easily so wear a cover if you plan using it during workouts and weightlifting

    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.

    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.
