This trick is a very nice concept, I really wanted this to be completely invisible and to be done
close-up. It "can" look good but only in certain situations... This would not be my go to effect...
It accomplishes the effect as shown in the trailer, but they say you can do it "inches" away from
the spectator, this is not entirely true, you definitely need your space. Although if you make a
really good gimmick and don't hold your hand still for too long you should freak some people out
with this.
Overall its worth buying, but not something you'll depend on.
