I work from home and therefore my chair mat gets a lot of use. After 6 months of every day use it has several cracks in it. I am very disappointed. I noticed a small sticker on a new one in the store that there may be a guarantee for a year but if I had it I threw it away. Next time I will fill out the guarantee information. I still cannot believe it didn't last a year.
I work out of a home office. We just had new hardwood floors installed. I didn't want to chance scratching the floor with my chair casters so I bought this chair mat. It works great and my only gripe is that I would really like to have one about one foot larger in each direction. But this one will do for most applications.
Would have preferred a hard mat but this works well on a carpet. It is flexible when wheels move on it but works the way I need. The price was about right
