    I have been wanting one of these for years and I finally said enough is enough I am getting one! I have not been disappointed! It has been very helpful on my health journey! After looking into the different metal finishes I went with the brushed metal because I do a lot of rough work with my hands. It has held up well (I do put a silicone guard on it when I know I am going to be doing something extra rough). It was easy to set up and has been easy to use and maintain. I would highly recommend it along with the best buy-geek squad services.

    The battery life is great, the data is useful and allows me to wear this to sleep instead of trying to use my Apple Watch and running the battery down on the watch. The insights are also interesting with more and different data than my Apple Watch alone can give me.

    1- If you don’t like to have jewelry that is scratched or if you think that it would bother you, don’t get it. I have it for less than a month and it’s all scratched. Covers either make it too bulky or make the ring slide from the correct place. 2- Sizes are off. And using something to adjust will prevent you for charging. 3- AMAZING! To track your sleep, stress levels, calories, heart rate and more. It keeps you more aware of everything. 4- charging life so far is amazing. 5- Process of buying or returning in Best Buy it’s easy and simple.

    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!

    The Oura ring is amazing, I love it, I was thinking about this ring for a long time ,but I decided to buy it, so I recommend this ring to everyone. If I could, I would give ten stars instead of four.

    It’s great! Love how it tracks my sleep, stress, and ask me to confirm certain activities. It’s great, it helps me determine when I need to rest. I also live that there are covers for it so I can change the look.
