Overall would rate as average. Nice size for my application. Used for a couple of weeks and noticed some carpet creep and the shiny surface shows scuff marks easily. The chair wheels make indentations but they rebound quickly. The surface has a smooth comfortable feel that doesn't feel too hard.
Had this shipped so couldnt see before trying. Appears to be a good quality product overall but it wasnt firm/sturdy enough for my standard office chair--in just a few hours there were deep imprints from the chair wheels. It would work well on office flat pile cerpet but not on 3-or 4/8" pile home carpet. I have found if the chair mat can be rolled up (the way it was shipped) it likely wont be sturdy enough. Store service was very good.
After less than a week this mat is already buckling under the chair wheels. I purchased a thicker mat and expected it to be more solid. Also it was shipped unwrapped so all the dirt from the truck was on it and I had to clean it before putting down on the carpet. Very disappointing.
