    I’ve been using my Oura Ring for a few weeks now and I’m really impressed. The sleep tracking is incredibly detailed and has helped me make real changes to my routine. I also like how it tracks activity and recovery without being bulky or distracting like a watch. The app is easy to use and very insightful. Definitely worth the investment if you're serious about health tracking!

    Wanted to love this ring but ended up returning after 3 weeks. It does not accurately catch exercise and thought I was sleeping when I was not. It was comfortable but possibly too loose, maybe would be more accurate if tight, but I would only take the gamble if you are okay with having to return. It is easy to setup and charges quickly, nice look, just wish it was more accurate.

    The information the Oura Ring 4 provides, particularly on my sleep habits is very interesting and useful! Also like the tracking of heart rate and O2sat readings.

    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.
