Query: I wasn't sure what to expect for the money.

I have had these mats for a while and wouldn't recommend them. They curl up, warp, and slide all over the counter even with a damp towel underneath . They also don't stand up well to cutting as the knife marred the surface quickly. I should say that all I use them for is pounding cutlets between 2 of them. I purchased another mat from a cooking store and it was $10 for 1 but offers a backing that doesn't slide. It works MUCH better than these.
