After the delivery took long mistaken and had significantly exceeded the same period I can only say that the mat always is very slippery, but unfortunately one has the subjective tactile feel that you touch damp licorice and the mat is sticky. The feeling is confirmed when one tries to solve the mats in the car again.
Since therefore sets the feeling that significant residues remain on the dashboard in the car after a long use, and possibly a hot summer, I have the 3 mats that had ordered, rather laid on its side - a pity. I have to look for another solution.
