Used Oura Ring Gen3 Horizon Silver (size 11) in great working condition. Less than 1 year old. Some scuffing/scratching along the outside regular due to use. Have owned for about a year. Love the product and have upgraded, which is the only reason it’s up for sale here. Incredible sleep tracker. So much lighter and more wearable than it looks. Feel free to ask me any questions! Comes with fully functioning charger base and cord.
