In full disclosure, the effect does work. However, as mentioned is does require the purchase of an
additional phone app. That raises two questions. Why do you have to pay for the app if you
purchase this? And what this this purchase get you? To answer the first question, the app does all
of the work. This purchase will get you very little. It merely provides you a couple of jokers and
a couple of gaffs that you probably won't need if you own of the of other available decks that this
works with. This purchase doesn't even include instructions or routine ideas. So if you want to
use Bicycle cards with non-standard Jokers, buy this. Otherwise go straight for the app and choose
one of the other supported decks. As far as the app goes, it does work but it is very rough and so
obvious that even children will know it is an app. I wouldn't say that it makes the effect
worthless, but it's not nearly as hard hitting as I had hoped. It's more of a gag than a magic
trick. I wish that I could take back the $18 I have invested in this trick and put it into
something else. I feel quite let down.
