They claim that if the pan gets put in the dishwasher continuously that it could get where it may stick. Bull ***! One time in the dishwasher and you might as well throw it in the garbage and re-seasoning won't help.Everything sticks even butter. Don't buy this expensive stuff. They claimed that if you put it in a dishwasher it voids the warranty and all they have to say is SORRY. I was a Chef and I know cookware.works fine for awile then it dyes just like all the rest. Just buy a reasonably good pan and spend a lot less.
