Pans are great!  I have learned to cook on low to medium heat as advised by manufacturer and everything cooks perfect! I have purchased several nonstick pans including Calaphon and Ballarini - great pans but after a few years the surface begins to degrade.  Green pans are significantly less than cost those listed.  If all nonstick pans eventually fail ,I would prefer to pay a lesser price.  I have bought 4 more pans since this purchase.
