Im going to say I like how my copper chef pans look. After about 2 uses they do not docas the ads say so false advertising definite. They stick. They do not just slide around as ads says. Eggs stick severely. As for meat. The natural fat sticks to the pan and discolored it. As for finding a way to fully clean the marks just hasnt happened. It also scratches unlike the ad says it doesnt. For false advertisement I think the company should replace all pans every few months or quit lying in their advertisement. I see a class action in the future.
