I watched the 'get nyman' dvd and was highly dissapointed in the material, he has been lecturing the same material for yonks! He is a fantastic performer and his use of subtle moves and patter are the Bomb.
I couldnt see how you could call his chair test a chair test, it at best (even without an out) was a 50/50 chance...
I completely agree with arkham that the material is mostly mental magic!
Although I Agree the material was a little weak, it is meant to be based on the psychology offered by of one of the Greatest minds in the industry.
The material is what you make it, the routines offered are routines that are sure fire and perfect for most levels of performer, I personally believe the dvd is a good price as you get your own private lecture.
Some dvds retail at 3 times the price the material is not sure fire and the performer just drabs on about the method rather than the performance (which is for the most part the importanty).
