I love love love the Copper Core line.  It is elegant along with being fabulous cookware.  The pans are heavy (both in build and weight), but that translates to even cooking.  They are not non-stick, but clean-up has been easy.  If there is food stuck, a quick soak while we eat, and everything just sponges off, barely any scrubbing ever needed.  As one reviewer said, just hit the pan with some water while still hot (think, de-glaze), and food lifts off.  These pans will last beyond my lifetime.
     My only negative is I was building my own set of pans, a la carte.  I do not need a big pasta pot as is included in all the sets.  I do need a small 1.5 qt saucepan for sauces, small veg cooking, and that is no longer offered.  It is a versatile size, especially when cooking for only one or two.  Customer service said there wasn't much demand so it was discontinued.  I am disappointed.
