I was disappointed. The adhesive areas are located on the sides. You have quite tense, so it rests on the skin, the patch during adhesion. Once you glued to remove it and re-glued, the adhesive effect is (at least for me) is so low that I then have to constantly re-re-stick the patch.
The heat effect I hardly felt. I am probably more a fan excessive heat such as the ABC or a mudpack. Who moor cushions are too crass is, with this product one probably happy. Everyone else should really save this money.
