This is a decent product for the price. I purchased to use primarily at home. After having a rolling chair and no mat I was determined not to ruin any more carpet. The only con I have is for the shape. Since I have a small desk at home the portion that fits underneath the desk is to short. There is about 11 to 12 inches deep of unprotected carpet. The remainder of the area is just perfect. Great buy!
We use this mat on our hard wood floors. We are at the computer every day. It works great. The only problem I notice is that it slides around. I am going to try to figure out a way to keep that from happening. For now I just readjust it every couple of days. Great mat for the money!
