Less than one year old Oura Ring 4 in silver. Charger included. This has been factory reset. Shows some signs of wear and scratches which is very common for Oura rings when worn every day. Battery life isn’t as good as when I first got it. Have to charge every few days now versus every 7-8 days but other than that it works perfectly for tracking sleep, fitness, and all other features! Please note you need to purchase a separate subscription from Oura.
