mom for some time neuralgia neck and shoulders enhanced by heat. I bought her this article, as soon as she sits down she puts it, it really feels good, she puts it to 2, that is enough. I tried it, 3 it's too hot for me, but it's very comfortable, I feel I'm going to buy me a winter evenings watching TV. It is very well done, very nice, you can close it with pressures but also closes magnetically. Only regret, we should sit for the carry, when a charging system?
