The battery is dead, so I haven't been able to confirm its operation. Please understand. I received this, but I've kept it at home without using it. There are some minor scratches on the back and glass surface, though they are not very noticeable (see photo 4). The belt part has deteriorated. It can be easily replaced, so I recommend replacing it with your favorite belt and using it (see photo 5). Please understand that this is a used item before purchasing.
