    I absolutely love my Oura ring. It provides so much insight which can help me increase my activity, meal choices, analyze stress and more. It’s comfortable to wear and if you have a friend with an Oura ring you can help each other keep motivated by seeing their activity.

    Obsessed with my Oura ring! I had an Apple Watch for years but I love how the ring fits in more with my everyday outfits. I’ve found it to be super accurate & insightful about my activity, sleep, vitals, stress levels, etc. It’s comfortable & the battery lasts days. I love love love it!

    Used sizing kit first so I would get the right fit. It is pretty accurate on everything and when I was sick it told me I was having strain on my body prior to me knowing I was sick. 10/10!

    Make sure to buy the sizing kit first, to make sure what you buy will fit properly. I've been wearing this ring and using the Oura app to monitor my health. Pretty accurate and easy to setup. If you connect to BT often, the ring will need to charge more frequently. Solid purchase!

    Very good product only get the factory warranty if you order through Oura, Best Buy does offer their peak squad which I forgot to do. It also alerted me to be getting sick before I was feeling bad.

    It’s been almost a year since I have owned it. I am 52 and at 51 I started to have health issues. Seeing notifications that my body was stressed made me go to the doctor and I was able to get it under control and therefore my sleep and energy improved. I luv the battery life it’s better than the watch but I use the watch for my fitness tracking. It also still worked when I lost weight and my finer most likely wasn’t a size 10 anymore.
