Sorry, I wanted to like this and be able to use it, but it works one quarter of the time, taking several pushes of the circuit to ignite the paper. the 'button' switch is primitive, unsafe and unusable. I will have to construct a new one with a sure-fire (no pun intended) button to enable ignition every time.. this gimmick is a nice try and idea, just not worthy of selling to trusting magicians at this stage. When dealing with fire, this should have been perfected before marketing... thanks.

totaly flat, works excelent, I put it into a book (I have to cut a rectagle in the middle of 12 page to fit in), some flash paper and POW!, you get a terrible reaction from the audience.
Flash in 2 second.
