Stick with metal pans!
I'm so glad I bought this used for $2 vs. new. It looks cool, and the Kitchenaid brand was a plus. Muffins and cupcakes don't brown like they should. The texture and crumb are different. The pan doesn't effect taste luckily. Storage is a problem. Using non-stick sprays leaves a sticky finish to the muffin pan eventually that does not come off in the dishwasher - which would also happen with some metal cupcake or cake pans as well. I do not recommend this at all. If anyone wants to pay shipping, they can have my pan! I'll stick to metal pans.
