I received these pans for Christmas.  I used the large frying pan to prepare spaghetti sauce for dinner.  The pan heated evenly and of course nothing sticks.  It's nice having the lid to use for keeping things warm at low heat or keeping sauces from splashing when cooking.
Like The Rock griddle, which I also received as a gift, cleanup was easy with the non stick surface.  The smaller pan is the perfect size for preparing smaller servings of scrambled eggs,etc.
