Were to start? The effect is good. The instructional DVD is terrible. The DVD shows a basic handling with no dialog. You read as you watch the performance. Music played in the background and is very distracting. This is not a trick for beginners. The presentation shown on the DVD requires good misdirection- I had to completely re-block the handling to fit my performing style. Mr. James should have spent more time putting a good DVD together with discussions on different handling options. You are basically on your own once you have seen the basic handling. The AD is deceptive it is not as clean as shown, for understandable reasons (I can’t say anymore without giving away the secret). The link is very visual and is clean and looks just like it does on the demo. What you are paying for is a nicely made gimmick – I am not sure how long it will last – that is my main concern. My main disappointment is the instructional DVD.
