Does not slip
Looks good
Negatives:
Smells disgusting even after days of chemistry. On the first day you had to hold your breath in the bathroom because it smelled so extreme and pungent. 2x processed with vinegar and 3 normal Duschgeaenge undnes still smells something.
The stench is certainly auhoeren sometime. But what is me most disturbing that the water does not run under and on the mat after showering yielding occurs morning to the mat and gets through the cold water. And 24 hours later. I will lift up the mat now every time and place from diagonally to the wall, so that it can drain.
I can say so far unfortunately not buy recommendation.
