    I’ve had my oura ring since September 2025, 8 months now and it just now started disconnecting and shutting off by it self multiple times a day and it was amazing when it worked but now I’m upset it just isn’t working how it used to and I have taken great care of it!

  • Great Ring - Not So Great Finish

    I love the features and ease of use. My main complaint is the finish. After two less than two months of use and taking it off any time I’m working or lifting anything, it’s still pretty scuffed up and not appealing. Not noticeable from far away, but it still bothers me. It’s faired better than my wife’s ring though. She has the gold one.

    I absolutely love my Oura ring, I debated between a Oura ring or Apple Watch and I’m so happy I chose the ring! For the price vs a Apple Watch it has so much more functions

    Absolutely love my ring ! If you are torn between spending the money and not just do it ! The app has helped me with my sleeping habits, knowing when I’m stressed and so much more. Just do it !! I have a cover over my ring to protect it from scratches and I’ve added some rings so it gives off more of a feminine look.

    Pretty handy. I like the personalized insights, wish they were a bit more personalized and varied though. The subscription fee is unnecessary but at least is HSA/FSA eligible. Powerful at detecting minor changes, very sensitive. While it is good to get a visual summary of how your body is feeling to force yourself to be kind to your body and listen to it from time to time in a busy stressful life, I'm not sure if it biases me to expect that because I'm not at a 100% or have "minor strains" I'll be extra tired that day (chicken and egg).
