After years of having stainless steel frying pans (mostly scanpan which were ok but my large one warped really quickly), last year I cracked and bought two Circulon non stick ones.
I'm never buying non stick again. These are pretty good quality and not the type that peels (not teflon) so I thought they would be ok. The problem is, you can't heat them
my large one has been used to cook steaks etc and is no longer non-stick. They did warn me at the shop I bought them that you shouldn't 'over' heat them, but given they are labelled as oven safe to 400 degrees I figured they'd be ok for frying.
I've since found plenty of reviews online from others saying similar. Next time I'm going to try something else.
