So, this may be a biased opinion. I will do my best to make it as unbiased as possible.
I
really really enjoy this control, for one may reason. It is fluid. Parental Control is sleightly
(slightly, I know) knacky, but once you get that knack down, the move just flows. And to a lay
person, it's undetectable. This wasn't made to be a magician fooler, this was made to be a workers
control. John G and Chris Kenner both have similar moves, but this control can be done with multiple
cards. There are other variations between the moves, but, I can't get into those bits for the sake
of secrecy.
Some people might point out that it is a short download. I think Sebastian
covers everything quite well, and the beauty of an instant download, you have the ability to move
throughout the explanation at free will. Rewatching parts that you want. So yes, this might be a
short download, but that doesn't affect the teaching and the quality of the move.
I use
this. I love it. I recommend Parental Control. (also, the Parent Trap routine is a great routine to
do with any deck at any time with no set up)
