The seat cover with 2 stufigem switch relatively easily installed in the car. The heating works well and quickly. Within 2 minutes you can feel the heat. A real difference between the heat settings could tell ichnicht. Unfortunately, the seat pad keeps poorly on the seat, so you if they have been previously drawn smooth warp even when Just sit down. Unfortunately, the fixtures do not give the necessary support. Possibly by the support was broken, unfortunately after less than 2 months and no longer heated.
