It was half price and I needed some for the office and home. Have only been using for a couple of months - as recommended using on low pile carpeting. It is rated as an ECONOMICAL mat and I expect to get about a year's worth of service. A great value for the price I paid.
This mat really stays in place because the cleats work well. However the cleats are very sharp and will bring blood when trying to unroll it. Needs to be sold lying flat. Be very careful!
I am very sorry I purchased this chair mat. My old cracked mat had more support than this new chair mat. I wish I could return this mat and purchase another mat that was perhaps thicker more substantial. One that will not allow the wheels of my chair to sink into the mat.
