Heating pad for your arm.

This is a heating pad for your arm and shoulder area. I bought it because I had frozen shoulder and I was misdiagnosing myself, and I thought this would work. (Physical therapy worked) anyways it gets pretty hot. I believe it turns off halfway through the night there’s many settings. I only used it a few times. Works fine. The only thing missing is the strap that connects around your neck. It was very uncomfortable, so I took it off but it stays up on your shoulder anyway.
