Oura Ring Heritage Gold size 7 Gen 3. NO CHARGER AND NO WARRANTY. Ring was used for less than a month but is over a year old. Everything works perfectly fine but I did notice what seems to possibly be an inner crack as shown on images. I reached out to oura and they can’t identify what it is and said I can continue to use the ring as usual since it’s not cracked on the outer side. I showered with it daily even after noticing and never had issues. Battery lasts about 5 days. Comes only with box, box is slightly damaged. Charger can be purchased on amazon. Keep in mind when purchasing charger, it has to be charger for size 7! Any questions please ask :)
