The pans are excellent at being non-stick.  But they are very hard to clean.  A soft sponge looks like the pan is clean, but when it dries it's still dirty.  I clean things well, so this is a very odd occurrence to me.  I like everything about the pan, but it simply doesn't stay clean well.  I'm not talking about things sticking to the pan, but when you cook bacon in it, the fat actually stays on the pan, even after cleaning.
