I purchased the Copper Chef square fry pan and the accompanying round skillet. Have cooked many times in both pans and am very impressed with the ease of cleanup and the uniform cooking with the following exceptions: the bottom of the square pan is not flat - the center is high so all liquids and oils pool around the outer edge. Sauces and other dishes needing even mixing are difficult. The outside is not easy to clean, the fry pan's outside is easily stained and collects burn on food and when heated is impossible to remove. Still for flipping omelets, pancakes, etc. it is a dream come true. I have never had anything stick on the inside. Too bad the outside keeps the pans in the drawer and not on the pot rack.
Bottom Line: Yes, I would recommend this to a friend
