Oura's customer service has been great! My Oura ring 4 died after 8 months of use. I notified them and immediately started to address the issue. I had to submit some simple information and they determined that I would be sent a replacement ring free of charge. No jumping through hoops! The only reason I didn't give 5 stars was due to the fact the ring died so quickly. But other than that, they were a pleasure to deal with.
