I have the grill, griddle and waffle maker. Mine are the 8 inch models. These take a few practice runs but overall, all three are great. The waffle maker cooks some items better and more evenly.
Just a tip - mustard inside on the bread makes a great grilled cheese sandwich - I’m originally from York, PA and that’s the way we always made them - the mustard gives the sandwich just a bit of a peek up!!!
