The mat makes qualitatively what ago, and is slipping through the rubber coating on a smooth surface.
The only drawback, which was already listed in other reviews also is that the mat actually dirty quickly due to the relatively bright surface.
My advice here, take the mat she sprayed a with a not too aggressive detergents and cleaning them carefully with a high pressure cleaner, let it dry and almost as new !!!!!
Clear 5 Stars in my eyes!
