Cheap 4, 8 or 12 cue fireworks firing systems from eBAY - unboxing and buying advice for beginners

If you're wondering what the cheap as chips firing systems are like (typically sold as 4, 8 or 12 cue systems) then in this video I am unboxing exactly that. These make reasonable starter systems however are not without limitations because of their low price, as I discuss here. I'll also run through a few features that better (and more expensive) 4 cue based systems have as this is not immediately obvious to the beginner.
