The worst piece of non-stick I have ever used. We have begun replacing our old original calpahlon and have been thrilled with the all-clad up until this junk. Granted it has the core of the the stainless but the non-stick finish has "varnised" and as such is useless. We are accomplished cooks and use our pans daily sometimes all of them. Treat them with care and know how to preheat properly steer clear of this pan.
