Cleanup is easy, too! I don't know what the tray is made of
, but the food just seems to fall off of it when it's rinsed off. We did the "buy one get one free" deal, so we always have one ready to go. For about $24 for both (including shipping) I think the Magic Crisp Microwave Tray is a winner in terms of the texture of the food produced using the convenience of microwave cooking.
