Can anybody tell me how they work? It seems like a good idea to pick one up, but i want to be sure i understand it and am ordering the right thing if i'm gonna spend about $75 on it... how do they work? have a reptifogger and a zoomed UTH, how does the controller attach to them to control their output? this is what i'm looking at picking up, anybody have a warning i should know of against that product? Thanks guys!
