I am happy with this purchase of a dangerous trick. The detection method that comes with it works
well. You can add another method to have two. The DVD also tells of an idea to add a little more
safety to the effect. I liked the way this version looks and performs over the others. I would
recommend this to anyone who wants to try this effect. There is a chance you could mess up but it
would be a mental mistake not a gimmick. That is where the safety tip would help.
