    Have nothing but amazing things to say about Oura. Its expensive… BUT HEAR ME OUT. What is better than being in-tune with your body. 12/10 would recommend anyone. If you are hesitant because of cost, pull the trigger and thank me later

    I like the Oura ring for its functionality to give me data on multiple statistics like sleep, exercise, daily goals achieved, and my periods. Best I like is it giving me reading content to learn more on different data points

  • Great health ring, questionable battery life

    Amazing ring. Great stats on stress, heart health, sleep (with REM cycle observations), activity tracking/sensing/recommending, and activity sharing. There are great features this has that essentially replaced the need for a fitness watch. My only qualm is that mine within a month of use has had its battery deteriorate to losing charge within a day although it is estimated to last 7-8 days. So that’s a bit strange and inconvenient. Looking to see if this is just a software issue or a hardware that needs fixing
