I bought another brand of copper skillet just to try out and I was hooked on copper pans. It has held up very well too. My copper chef boiled egg maker though has not held up well. Seems the spot that has discolored is probably where the heating element is closest to the copper section. Still works fine but has that hot spot (blackened). My sister on the other hand bought an entire set of copper pots on sale last year by another maker and she loves her pans too. I also bought another brand electric skillet as with this brand you can take the skillet off the heating element and use it on the stove or oven. I don't think Copper Chef's electric skillet you can do that. Have been looking at their cookie sheets though as it seems they're the only ones offering them so far.
