Owned size 8 for six months and owned size 11 for one year but only wore for two months. I bought the size 11 to wear on my index finger but, it was too big. I bought the size 8, already having a size 8 in black.. Perfect working condition, connects with the Oura app, Comes in original box with original charger and cord. if you have any questions, please do not hesitate to ask.
