It seems to be a great product...but I will withhold final judgment until I see how long it takes before it starts to crack and discolor as all chair mats eventually do.
I'm honestly appalled at the high cost of chair mats in general. That said this mat is honestly too thin for my use but I knew that to begin with and refused to spend more for a chair mat. It's a fine chair mat for what it is but used on a medium pile carpet like I have it's going to get noticeable dimples that make it a little hard to roll the chair. But since it's not meant for medium pile carpet I can't really hold that against the product. I can hold the general price of chair mats against the industry though. *shakes fist*
Works ok. If you sit in one place for a long period of time the wheels on the chair sort of sink in making it a little difficult to move. At least it isn't cracking like the one I had to replace.
