Unfortunately, far too short a life.

When I bought the Ridder bath mat flatfoot aloha in June 2013, I was fully satisfied. The material from which the deposit is made, felt very high quality and also the skid resistance was excellent. After several months stepped out of the mat from an oily liquid and the material was over time getting tougher. The adhesion to the tank bottom can now by more and more, as well as the slip resistance. After a year of useful life, the liner was brittle. I can not understand why you are 3-year quality guarantee on this bath mat when the material is brittle after only 1 year and is about to crumble? I have the mat always treated properly, taken after every bath out of the bath, rinsed with water and stored dry when not in use. Now I have to find a good new bath mat, hopefully by holding a number of years, because safety is always less assured with my flat tire aloha. A year ago I would have forgiven even 5 stars, now only one still.
