Pros:
this effect looks good under perfect conditions
cons:
you have to create a gimmick that is far from sturdy, the least they could have done was include a well made gimmick.
You have to ditch a fairly large object in order to show your hand empty.
Most of the effects shown can be accomplished with a little sleight of hand.
Basically, buy this if your stupid.
