Oura Ring Gen 4

Selling my Oura Ring 4 in Ceramic Cloud, size 8. Purchased directly from Oura in December 2025 for $499.
Condition: Pristine — no scratches, dings, or signs of wear. Works perfectly, full sensor accuracy, no issues of any kind.
Included (100% complete, original box):
- Oura Ring 4, Size 8, Ceramic Cloud
- Original charger + USB-C cable
- Original box and packaging
- Instruction manual

Membership note: Oura's membership is tied to the account, not the ring — it does not transfer to a new owner. You'll need to set up your own Oura account and membership when you pair the ring (new members typically get one free month). I'm not able to transfer my remaining subscription time.
Reason for selling: Got the data I wanted out of it during the last 6 months and decided not to continue.
