Purchased before using new 12” one…rather bittersweet 
Experience…l use combo of olive oil and butter and it
Remains nicely on skillet bottom vs. rolling to sides, so, foods cook nicely, especially fish, however neither of my
Pans know their supposed to be Non Stick, so l can’t recommend them as it’s difficult to get the grid lines
Clean even after soaking in warm soapy water and they
Are rather heavy if that’s a problem for weak or elderly
Hands. Have non stick pans where eggs slide around and
Easily clean but the non sticking doesn’t last very Long..
So far no luck with that process….
