I purchased this pan and put it right to work. The muffins slid out of the pan with no effort and looked great. I just wish I could say the same for the pan. After only one batch of muffins, the pan is already discolored, and scrubbing is not making it go away. I'm really disappointed. I know that the looks of the pan are not nearly as important as the food. Still, I thought I was buying a decent quality product that would hold up better.
