I use this produt daily. It serves it purpose but overall flimsy. It will last about 4 months then it will start cracking which causes a problem with triping if your shoe gets caught on one of the cracks.
Returned product because it smelled terrible and continued to off-gas the entire week that I had it smelling up the entire office. Also caused eye watering sneesing and other allergic reaction symptoms. If you continue to sell this product there is no question that you will be sued for a defective product.
