Considering the environment Oura is operating in, they are top professionals.I am using their rings for the last 4 years and have always been treated very good. On this occasion my gen. 3 ring had a battery failure. Even though it was +2 years old, I was offered a replacement. In less than 2 days, a ring was shipped.That is why I keep coming back, even though prices are high. The quality and service are outstanding.Great service, THANKSJakob
