I already had a couple of occurrences when my old Oura ring had battery issues. As all those rings I was purchasing with Oura directly - the replacement process was quite transparent: they were checking the ring's status online somehow (they have access to it via app, I believe) and then just sending me a new replacement ring. The old one I could then just recycle later. I.e., I was never staying without a ring. If I buy it from Galaxus, will the warranty process be the same? Or will I have to send my faulty ring to Galaxus for a test before I get a new one? The price and delivery time is much better here, but I would not want to stay without a ring for a prolonged period of time if something happens to it.
