I have the smooth...radiant heat cooktop after having had both electric and gas. I love it and won't ever go back to gas or conventional electric stove. It is SO easy to clean...just wipe it with a wet rag. There is a special solution to use if spills get cooked on. I've had this one for 7 years and it still looks brand new. I actually do use a cast iron pot on mine and have had no problem doing so. I also use all of my 20 year old pots and pans and a big old steel wok. Check out different manufacturers to see what they recommend. Bon appetite!! KT
