I didn't know before I got mine that you can only use stainless steel pots and pans on it. no aluminum at all. it can melt. I lucked out and got a set 1/2 price. great. well food tends to stick to stainless steel. it does clean up great though.
i did find a small and large Oneida teflon coated skillet though. they have stainless steel bottoms. it took awhile to find them because most products don't tell you what they are made of completely.
the tops get dirty very easily. you will find yourself cleaning every time you cook. well, after it cools down which takes a long, long time.
otherwise they are great! :shock:
