Oura Oura 4 Silver Ring

Modern band with a smooth polished finish. Durable metal design for daily wear. Smoke free, pet free home Works great charges great! I just upgraded to the Oura 5. Pictures attached show that it does charge. I charged it on the five ring charger so it charged slow. You’re technically not supposed to be able to charge a four on a five charger though it worked just slow due to being on the wrong charger. I no longer have the charger to this ring. They are available on Amazon.
