These work great. I have done a few pigs in one. Its pretty fool proof and turns out delicious. There is a highend seller of cajun microwaves. Top quality but pretty expensive. I met him at a crawfish festival and they were pretty awesome units. http://www.cajunmicrowaves.com/
At first I thought you had found a microwave dinner that was actually good. Thats a pretty neat thing there I would like to play around with one.
