They sort of suck, I think. As was mentioned, you have to clean them out every time, and god forbid you use any sort of cheese in something like a panini, as it will burn and stick to the "non-stick" surface every time. It also doesn't cook evenly at all... the bars will burn the part of the meat/sandwich while other parts aren't cooked as much. Have you ever seen what comes out of a regular grill after each use? I think the Foreman grill just has a nice little grease/fat pan that shows you all that is expelled, but I can't imagine it's much more than what happens normally.
