pros

1 visual
2 end up clean from the point of view of the spectator
3 they provide u the props u need to make the gimmick , u just have to have some tools to utilize those props into propel gimmick


cons

1 not really practical
2 you must have a distance with the spectators
3 you must constantly move and shake your hand a litle bit while showing the dot , otherwise you will have to do it on a very dark place so that they cant see the gimmcik
4 its quite a fragile gimmick , be ready to reconstruct the if somehow the gimmick is broken
5 you cant do this on windy environment

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.

the trick itself is strong and easy to do I have worked this and it gets great reactions just as long as you make the gimmick precise their will look just like the trailer .
