Silver Soxai ring, size 22, Bluetooth compatible, includes USB charging cable. - Model: R11221 - Size: 22 - Color: Silver - Bluetooth: Compatible - Accessories: All included. Thank you for viewing. • Details There are some minor scratches, but I tried to be careful to avoid them. I purchased it last July and used it until November of last year. In fact, the battery lasted for 7 days. The smartphone connectivity and the accuracy of the recordings were not a problem. (Connectivity has improved since the Soxai ring 1.1 model) I am selling it this time because the size doesn't quite fit.
