Oura Oura Smart Ring Gen 3 Size 7 Heritage Black with charger

Oura smart ring for activity and sleep tracking. Sleek black finish with inner sensors. Comfortable band-style ring design. Syncs with Oura app for insights. This has been worn most of the time since I bought it, so I’ve tried to capture the wear marks in the photos—definitely not new but still works great. Probably the most detailed sleep data I’ve gotten from any device. You might be able to buff out the scratches if you’re handy.
