These mats are great! They don't stick, they don't slide, and they don't stink, which makes him perfect for the job that they are designed for. These are easy to clean, and they really are non stick, I have use them several times now and I can tell you but they are made very well, being thicker than ones that I have on previously. This is a good set for people who like to bake often, or for just anyone really who wants a good set of nonstick sheets.
