I love these so much.  I have not even touched one of my regular pans since I've bought these. I've fried chicken in the large one, baked cornbread in it, everything you can imagine!  I even used the two smaller pans to make panini's.  I put the sandwich in the medium pan and heated up the smaller one to use as the press.  I oil them lightly after each cleaning and after a few months of use I have yet to have anything stick to them that didn't easily scrub out.
