Perfect Brownies

Yes, I admit I can get easily sucked into infomercials, who doesn't? This was a rather interesting one which I am going to order called the Perfect Brownie. It's genius! Basically you can cook the brownies in a grid-like formation so that they come out baked as pieces and each brownie has the edges. Also, the bottom pushes up so that you don't have to transport them to another dish. I mean seriously, I know I sound like an ad right now but why haven't I heard of this until now?
