This product does not move once you put it down. That is the one thing I really like about it. I would recommend this to anyone but just be careful handling because it will stick you and it hurts alittle. I guess that is why it will not move. I think the price is somewhat high.
I needed a replacement for a chair mat that lasted a long time and was breaking up. This one is a bit smaller and I believe thinner and more flexible so far it's doing fine. The smaller size is not a factor; I actually like the smaller size. A definate plus it was on a half price sale.
I have had this mat for about 2 years. I work at least 5 days a week with my chair sitting on this mat. The mat protects the rug and allows my chair to roll more freely. After two years I need to buy a new one. As plastic mats in the past this one too crumbles. My next mat will be a higher priced rubber mat. "You get what you pay for" as they say.
