    I decided to buy one after being influenced by my friends! It’s a really cool device and I like being able to see my stats + sleep score. Only thing is it’s little uncomfortable during reformer Pilates when you’re holding the straps and the rose gold gets scratched very very easy. Besides that it’s great!

    I love my oura ring. I wear it everyday. As someone who use to not wear rings, I was comfortable wearing it after 2 days. I always am scared it’s gonna slip but it never does even in water. I love the app, def a great buy! It can scratch up but I have it in gold and you can’t really see it. Plus you can buy ring covers on amazon

    The Oura ring is a fabulous piece of self-care technology that looks good too! It shines brightly among the ‘fitness tracker’ options. The app is user friendly, very educational and supports achieving your personal wellness goals!

    Great product so far. The battery life is amazing. I’ve compared it to my watch and it is almost perfectly synced. It’s lightweight and I forget I’m even wearing most of the time.

    Love this ring! I have sleep apnea and wanted to track my sleep. I have apple and garmin watches but don't want to wear to bed. This ring and app tracks a lots of biometrics. It gives me ratings on stress and my bodies recovery. My activity levels and detailed sleep pattern to the minute. The stealth ring for men is durable, however, does have propensity to scratch. Recommend the latex protection covers on Amazon for wearing for golf, yard work, etc to protect ring.

    I have been on the fence on whether to buy a smart ring or not and I’m glad I finally did. It helps immensely that, regardless of which OS your phone runs, the Oura Ring app both sync seamlessly with your phone’s native Health apps. It’s comfortable, light, durable, and the app has top-notch health insights and metrics (as a health IT specialist and informaticist myself, this is a massive positive for me). My only concern is the long term wear and tear of its coating/material but was able to grab some ring sleeves to lessen it especially when wearing it at the gym.

    I absolutely love my new oura ring. It’s not bulky and it looks like a regular ring. I love how it tracks my steps, sleep and stress. It also has a feature that allows you to track your meals. This ring is definitely a game changer. At first I did a fitting for it to fit on my ring finger but I saw reviews that index finger is better. And I agree!!!

    LOVE LOVE LOVE! It is so worth the money. It is comfotable and light and you barely notice it after wearing it for a while. The one thing I will say is that you have to pay for the subscription to Oura but it is so worth it. The data you will get will change your day-to-day living and choices. Would definitely repurchase.

    This is a nice way to stealthily track your activities / sleep without needing something large on your wrist. It doesn't emit too much light, but there is some light you can see from under the ring, but it hasn't bothered my sleeping yet like my watch did.

    I had gotten myself an oura ring and when my husband saw mine he wanted one for himself so we went and got him one and he is absolutely obsessed! I use it for cycle tracking but my husband loves seeing his sleep patterns and calorie burn. We will definitely keep buying Oura rings as they continue to perfect they’re technology.
