    The Oura Ring is solid if you just want an easy, comfortable way to track your sleep and recovery, but not worth it if you’re looking for heavy workout features or don’t like paying a monthly fee.

    Great ring to track your health and activity. I went the ring route because it’s easier to sleep with it on opposed to a watch or bracelet. This thing picks up a lot of health stats. Happy with my purchase.

    Great product! The Oura Ring is very comfortable and easy to wear all day and night. I love how accurately it tracks my sleep, activity, and overall readiness. The app is simple to use and provides very helpful insights for improving daily habits. Stylish, lightweight, and truly useful. Definitely worth it!

    I've owned this for a little over a month now. Fantastic tracking overall. I've not noticed any inconsistencies with it yet. However, you MUST take it off if you work with electric impact wrenches or you may damage the sensors. Other than that, great product!

    This ring is a game changer and life changer. I got it for my 54th birthday. It made me aware that I might have sleep apnea, by showing me that I was having disturbances in my air while I slept. This information lead me to have a sleep study which did indeed say I had sleep apnea. It’s also making me aware of how important my sleep and my heart rate is. Having sleep apnea explains why I’ve had high heart rates at night.. my body was in distress from lack of air. I want to have a great cognitive future and having air while sleeping and getting the right amount of sleep is a great start.
