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:

MIne is five years old and I also use the razor and Cerambright cleaner with a paper towel. Have a couple places that wont clean but it cooks great.

Now you won't have to clean those drip pans. Ugh I could never get them clean and always had to put them in self cleaning oven to get really good and clean,
I have the double oven and it is great for big gatherings. I have not used bar keepers friend. It does not take much of the cleaner so I just buy what they recommend.
It also came with a metal scraper and that is what I use.
have fun!

I have a friend who has used a smooth cast iron skillet on hers for years with no problem. The instructions with my cook top say not to use pans with enameled bottoms or any type of glass or ceramic because in rare situations they can melt and fuse with the cook top, and the damage would be irreversible. So if you think there's any chance you'd ever let the liquid boil out of a pot, that might make you think twice about using those kinds. At least carefully read through your manual before you decide what's okay. My current one is an Amana, and it was in the house when we bought it - no manual. If I remember right the one we bought for the previous house was a Whirlpool.
