I had an Oura Ring 4 for a few weeks, and it's one of the only tech gadgets I have ever returned. Thankfully it didn't swell and trap my finger, but it hit some kind of internal deadlock that didn't go away until the battery fully depleted over several days. The repeated-knock gesture to hard reset didn't work either. Best part is, my wife hit the exact same bug just a week later. I don't see myself buying a smart ring ever again.
