I was one of those who loved and indulged in Mauviel copper.  But it does need cleaning to keep it beautiful and it is heavy.  I had supplemented with a small copper core fry pan a few years back and, following a recent kitchen disaster, needed to replace a saucepan.  This copper core saucepan is just PERFECT!  I'm sold on this product and, should any more kitchen disasters occur, will be recreating my pan repertoire only with copper core!
