Worn for five months, video included to show scratching on ring. Oura rings do scratch very easily. Ring has been factory reset. Oura ring sizes are different than normal sizes! I wore the ring on my pointer finger and for reference my pointer finger actual ring size is 8 but oura ring size 9 fit best. There are sensors on the inside of the ring that require a slightly bigger size to fit correctly. Includes charger, info packet, instructions, ring, and box!
