I have it.. there are two versions one for the pros and one for the beginners.. the pro one isnt so difficult a little practice and ready to go.. is like from 1/10 I give 4/10 talking about difficulty..
BTW theres only one move that make the difference between the easy and the pro version..
I love performing it, its unbelievable I really love this effect.. =)
If u are planning to get it, then get it
