3 years is all I got. Oura Ring 4
Unfortunately my warranty expired so I have to get a new one today. Worth it? Yeah. It wouldn’t track my sleep anymore accurately, no accurate BBT.. I hate the fact that if you accidentally leave it on the charger, you’ll burn the battery which burns the whole system. I really hope they fix that….
Edit : Sorry, 2 years with Gen 4. I had a gen 3 and upgraded.
