I have to replace these mats about every 6-8 months. They crack and break. I have tried the expensive ones and the not too expensive mats. They all crack and break.
I am very happy with this product. I bought it to replace old chair mat that I had for over 20 years that had become brittle and started cracking. I have been looking for a while but was unable to find the size I needed until I came across this one online.
