    If you want a low-profile, high-quality health tracker focused on sleep, recovery, and overall wellness, the Oura Ring is absolutely worth it. It’s comfortable, accurate, and gives you real insights you can actually use.

    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.

    So far loving it! It's super light and do not even feel you have it on. Easy to set up, the app is amazing. Clean, easy to read and just the metrics you need. Others can get be a bit of data overload.

    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.

    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.

    LOVE my ring!! The only thing that I’d do differently is get a cover for it because it does scratch easy.
