Has anyone out there used them? Do they bake unevenly?

Becki

I have heard they do not. I don't know how it could with the pans being uneven. I was excited when I first heard about them. I have since then decided to just bake and cut. I think they will sell due to the "novelty factor" of them, but I don't see how they can cook evenly. My opinion.

That's what I was thinking. Thanks!
