I had bought the heat-Cape for my sister who freezes easily. The Cape itself is from the substance ago by good quality. The supply of heat is controlled by a switch with 6 steps. And exactly here is the problem: From heat can be no question. Even at the level 6 höchten the Cape was only lukewarm and therefore has a meaning, to provide warmth, not fulfilled. So I had the Cape to return, which went smoothly, it deserves Amazon kudos!
