I continue to be impressed with Oura. Something seemed to be off with the battery life on my Gen 4 ring. After a quick chat with "Finn" (their AI expert), my concerns were escalated with a promise of a response within 24 hours. Even though my initial conversation was over a weekend, by Monday morning, the Oura team identified an issue, and without any further engagement on my part, they asked me to verify my ring size and my shipping address get me a replacement. Most "chat bots" force you into frustrating conversations before escalating a problem. NOT so with Oura which was a true breath of fresh air. I've been an Oura owner since 2019. Every company should borrow a page from their book. Stellar experience all the way around!
