There are special cleaners that need to be used to get the best shine on them, but I have had one for about five years and love it. You can get the cleaning solution anywhere and it is cheap.

One weird thing is that I have some pans that will start to shake when water boils in them and some that don't, but I don't know if it is the top or the pan that is causing it.

All of my appliances are made by Bosch. I can highly recommend their brand.
