I've had this mat for about a month and so far it has been really good. I love the fact that it is clear and blends in well with my carpet. My chair slides very easily over the mat too. I would not pay anymore for a chairmat as they all only last a maximum of 3 years.
I was surprised at the prices for chair mats when I shopped around so kudos to Staples for offering a low priced chair mat that does the job. I've been using it for about a month and am satisfied for the price I paid. The cleats on the bottom make rolling on it a bit bumpy but I can live with it. You will see some deformations but they do go away. If they don't leaving it in the sun for a short while so it gets warm probably will remove them. Tip: I left it outside for a coule days where it wasn't in direct light to allow it to de-gas and shed the strong vinyl oder.
I like to look for value in my purchases. This mat was a little on the pricey side. Store did not have thicker mats would have to order on line or go to [@].
