I'll admit, the first few times I used it I certainly didn't forget it! I watched it like a hawk to make sure it didn't burn the food, because for some reason you can't just turn it off like a microwave or oven - you'd have to unplug it, take the food out, and let the thing run it's course empty, which I really didn't want to have to do. It worked just like it said it would, though. Only cleaning is a bit messy.
