This is a great product. He filled out his fonctions.Mais especially should always leave it in the bag because it is so hot that you could burn yourself. It is a pleasure to have the nice warm bed at the height of the feet. Amazon thank you because the first I had received was not working, and the return is so well organized that it was an easy child to have one in exchange. That was quick, and the return was supported by Free amazon. BRAVO
