    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!

    I love my Oura ring, it’s been really insightful to provide extra health and sleep information that I wasn’t getting from my smart watch. The battery life has been pretty good so far, and it charges up quickly.

    This is my fourth Oura ring, I love how most of the sensors are embedded and you don’t feel them at all, with each new generation I’m getting more and more information about my health and rest and sleep habits! I love having an Oura ring
