This is the second one that I have purchased over the years. My hardwood floors are getting old and I am using these to stop any future damage from our office chairs. They work great and last a very long time. My first one was purchased over 10 years ago and still looks brand new.
The chair mat itself seems fine. It was left in a folded heap on the porch in 100 degree weather - and over a week later it still hasn't fully regained its shape. I'm using on a hardwood floor - it seems to do the trick for the most part but slides around a bit and needs periodic re-adjustment. A bit overpriced for a piece of plastic.
