Did my girlfriend bought this Sitzheizkissen and we are therefore actually quite pleased. The heat output is classified by both the intensity and in terms of speed as well. The seat cover is hot after a few seconds and has less than one minute, the full (and that's quite hot) achieved performance. The only small flaws: - No dose possible (either ON or OFF switch -> via the mains plug) - The attachment (was the Seat Leon difficult hooks etc not hold - self-construction necessary
