I received this mat 2/18/2015 and about two weeks ago it suddenly cracked. I use it in my home and I am the only user. It lasted a little less than a year. I expected to get at least a couple years out of it but maybe I expect too much.
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.
