This one is replacing another mat of the same type. The other one lasted for well over 7 years before needing replacing. I consider that a pretty good product seeing as it is used daily. The only thing I didn't like about it is the fact that it discolored.
This mat has completely failed. Once temperatures drop below 65 degrees in office it chunks and cracks eventually leaving gapping holes exposing my carpet. The same thing happened to the original one I purchased. I had to jump through manufacture hoops to get a replacement. Staples does not handle replacement. Current mat is the replacement and it failed too. Bummer.
