    Have been using for two months to help supplement information about sleep for sleep apnea treatment. I have found it easy to use and appreciate the feed back I get via app. I follow recommendation to charge when taking shower and have not noticed any battery issue at this time.

    Readings are accurate as far as i can tell. More insight into overall health than Apple watch 11. One drawback is ive yet to get 8 days of charging from it. The most iver received was roughly 3.5 days. App is good and easy to understand

    Very happy with the Oura Ring. It’s comfortable, easy to use, and the sleep insights are especially helpful. The app is clear and not overwhelming, and the battery lasts several days. Overall, a great tool for improving sleep and daily health. Highly recommend.

    I love using this for cycle tracking! I dont know how accurate the step count is but it seems pretty close to my apple watch. I also use it to record workouts so i can see my HR zones but i still use my apple watch as well. Definitely get the ring sizer to know which size to get if ordring online!

    I bought it for my girlfriend around a year ago. The ring has been tried and tested and its a pretty solid ring , after the year the sensor stopped working but i have the bestbuy total membership so i got it replaced overall while the ring is working its really solid with everything tracking health stuff and also comfort as my girl wears it all the time except when recharging the ring of course.
