Nice thick chair mat for use on carpets. Cheaper thin mats seem like a good deal but will crack after a few months. Previous thick mats I've had last for years. This mat is even thicker (and more expensive) than my previous chair mat.
It looks good and grips well on my very low pile carpet. Of course I've only been using it for a week -- companies always ask for ratings very quickly -- so there's no way to predict how good it will be over time.
