good product!
I was attracted immediately by the appearance, I can feel the warmth through the outfit looking. So I ordered it right away.I am glad my felt is right, the material  is  soft, and less a minute after plug, it brings  comfort and suitable warmth to my back and shoulders. I have a quite few similar products  using boiling water or microwaveable materials, among them, i like this one most, it’s so convenient too, i hope next stage it can be charged by wireless 😂 (I don’t have pain problem, so I don’t make comment on it)
