I use this product at home in a computer room. It has meet my expectations with two exceptions: the mat slides out of position and divots are easily created by the chair.
I bought two of these chairmats in the early morning and left them in my car while I went to work. When I came out in the afternoon my car was filled with the noxious odor of melted plastic. The mats were soft and maleable and almost rubbery. A day or so inside and they're back to normal. So the message here is not to leave these mats in a car when the outside temperature is 109-degrees!
I use this projuct as a chair mat. There is not a lot I could say about any chair mad. The one thing I could say is that it was a lot easier to move around than the one it replaced
I placed my computer in a "closet" that is directly behind (when the door is open to the hallway)a door. There is beige carpet in the room and the mat is placed in such a way that the offset is placed under the door and the larger portio is where my chair is. Only problem with the setup is-I am in the way of the door opening the whole way when I use my computer!!
