Does anyone have this? If so, what are your opinion does it work?

I use the Babycake Cake Pop maker and I like it a lot.

As for the Bake Pop pans, the only thing I heard about them is that there are delivery problems (people don't get their order) and problems contacting the company.

Here's a discussion about them from this forum:

Bake Pop pans work great. You just have to fill them properly. Yes, it does take a long time to receive the pans (3-6 weeks to be exact). My guess is they're manufactured overseas. It's a lot like the giant cupcake making pan that was all the rage a few years back. I can say Bake Pop pans work and my kids love them (perfect for class parties, birthday parties, etc). My bet is they'll be available in stores soon.
