Oura ring 3. Ring works perfect I just got a new one. ring has scratches on it from daily wear but still looks fine on, 3rd photo (top ring is the one being sold) shows scratches compared to brand new ring. Will ship in ring box from my new ring which shows as a gen 4 size 8 but the ring for sale is size 9 gen 3. Comes with charger and instructions for set up
