This Oura ring is approx 1 year old. It is having battery issues meaning it only lasts 1-3 days on a full charge as opposed to the up to 8 day battery life Oura advertises. Oura is sending me a replacement but I’m selling my current ring in case anyone wants a very discounted ring or wants to try it first before they pay full price for a new ring. The color is faded. Charger not included.
