"Just what I wanted"
Having had 2 large ones for about 9 years with no problems at all, still as good as new, I was pleased to find this one to fill an awkward gap. I now can put hot pans anywhere without worrying about damaging the worktops. I am surprised other people have had problems. However I have never put mine in a dishwasher. I mostly just wipe them down each day with a cloth or occasionally with hot water in a bowl but don't immerse them in water. I don't usually cut directly on them as I use fleximats as I find it easier then to flex them to put peelings in the bin.
