I picked up one of these from a garage sale and figured it might be handy when rolling out pie dough. The mat is silicone in nature and stays put when it is on a clean counter (no flour on it) and then when putting flour on top, it is easy to roll the dough out on the mat. Performance I love that this mat stays put and does not move on the counter like fabric does. I had an older fabric mat with wooden ends on it, and it was so frustrating I never used it. I usually can not stand silicone when it comes to baking, but in this case, I make an exception. This mat is very handy and helpful. Ease of Cleaning This is supposed to be dishwasher safe, but I prefer to wash it by hand. It is pretty large so you have to figure out a method based upon the size and depth of your sink. It is possible to clean it well in the sink though. Durability So far it is quite durable and easy to store too- just roll it up and store it in a place where it won't be smashed. Design I think that it is a nice design. It seems to be well thought out and designed. Doesn't Stick I guess it is habit, but I prefer to have a little bit of flour on the top of the sheet so the dough is easier to move around and manipulate.
