I love my cast iron, but these pans are unbelievable performers when it comes to nonstick and quick release.  I won't cook scrambled eggs or omelettes on anything else.  I bought the tow-pack of 10 and 12" frying pans.  The only negative?  The pans come packaged together, and the handle of the small pan wore the coating to bare metal on the upper edge of the 12" pan.  Should't affect performance, but . . .
