The mat arrived with the rubber edge split/broken in two locations and the "entire" back rubber is cracked and flaking off causing the mat not to lay flat, exposing the coco on the back and insuring a reduced lifespan. I have had this identical mat for 5 years and repurchased it after the front coco & rubber wore thin. This mat is totally unacceptable and the poorest quality for such an expensive mat. I want a replacement or refund.
