After reading the great reviews, I purchased this lovely mat,  I've always had doormats made of this material so I knew to expect shedding.  Previous ones lasted years.   However, this mat is thinner than those I used before and clearly the fibers per inch not as dense, which was clear when I first stepped on it.  After only a couple of weeks it already has flattened and looks old.  Maybe I received a defective one given the good reviews.  Don't know if I can return it in this condition, but not what I expected for what I paid.
