I purchased my Oura ring on May 15, I learned to love it and keep track of my body. This was especially important to me as I just started a new health journey. The ring was great for the first two weeks but for some reason my battery kept dying ridiculously fast, and it got worse over time and it reached the point of only lasting half the day. So I figured I got a faulty ring. Naturally I would have went to exchange it but I already past the return/exchange period. So I did some googling and saw that Oura does replace the ring as I read in some discussion boards. I reached out to customer service via my Oura app and started with the chat box about my rings battery life, they ran a test and was able to confirm I had a faulty battery. From there the chat box connected me to customer service and they were swift with contacting me and sending a replacement. I’m very happy with the the results of this. Thank you.
