It kinda looks and sounds (and reads) like a pressure cooker with a little tray sitting in it. I'm not sure why you wouldn't just use a pressure cooker of your own (you can get little trays). One flaw is that they do tend to make the foods taste a bit like each other if they are cooked together. I don't mind that, but it is worth realising
