Been collecting Le Crueset cookware to use for 30 years. I currently have 4 saucepans, two dutch ovens, two casserole pans, a non-stick frying pan and a lidded paella pan (all enameled cast iron). Only the non-stick pan has any significant wear, as the coating is damaged and flaking a bit. Otherwise, just some minor chips, bottom wear and staining to the interiors. I always wash them by hand and am careful to avoid chipping the enamel, but I literally use everything on a regular basis and the sauce pans daily.
