Reading the other reviews, you may think words like "easy" make it an "out of the box" effect. I
urge you to practice the effect until it becomes second nature. The method is remarkable in its
simplicity, but building the muscle of the mind regarding the mathematics, and rehearsing the hands
as far as the "dirty work" is concerned, make it as clean as the demo. This is now my signature
card effect and will be yours as well if you put the eagerness to perform aside and put the ample
rehearsal time in.
