I can tell you this. American DJ is about the lowest quality cheapest price manufacturer you can buy without going to an unknown Chinese manufacturer. Don't get me wrong, they have their place in the entertainment industry, it's just not in the professional concert or theater area. ADJ's main market is lower budget clubs and DJ's. Unfortunately for your question, most of the experts around this website work in the professional theater or concert world. Although ADJ makes many fun products they just aren't relibable enough or bright enough to use in professional situations thus they are often the target of jokes around here instead.
Oh, I don't know about that. I had to create a large fire cracker effect for the 2007 Pageant of the Masters. American DJ's Flash Rope worked great for that effect.
