Since I have no seats in my car, I wanted a quick, easy and inexpensive upgrade. This seat cover all three criteria were met very well. I had long researched and then decided ultimately for this product and it has not let me. => Fits very well in the car seat => Is super fast warm after about 30sec. one notices first heat at Popo => I also feel the heat on the back (contrary to other opinions). Since I'm wearing a thick jacket, I feel the heat logically only after a few kilometers ... => Very good mounting options: Multi-Mount through horizontal and vertical tethers => No slipping: You must always be aware when a seat cover that this a built-in seat heating when it comes to "slippage" can not hold a candle. However, if you normally gets in the car and not "slip purely" can, then the cushion stays where it should be. => Three functional levels: off, low, high. I use only low and find that this stage already quite sufficient. One should not forget the plug completely to draw and make not only to "out" only.
My father has for years an additional heated seat cover, but this slip constantly and needed much longer to warm up, as it here. The following information may be important to potential buyers: => I have a Polo 9N, Bj.2003 => I am commuting and drive every day ca.80km => The seat pad I "built" for about 4 weeks and use it every day since - even with only short trips, since it is just warm very quickly.
CONCLUSION: I am completely satisfied, they can recommend and hope that the seats will reliably help over the winter to me :-)
