The effect relies on a clever gimmicked box that looks normal, but allows you to show the card box empty. You can not only produce a deck of cards, but anything that’s small enough to fit into a card box. The box can also be used as a switching device - for example, to switch small notes.
The accompanying DVD offers thorough instructions - many from the performer’s viewpoint so you can watch the moves and the prop in action. The moves aren’t difficult, but there are nuances that one will need to practice. Keep in mind that because the prop is made from an actual Bicycle card box, it will eventually wear out. I think it’s most practical for a formal close-up show as in my walk around sets, a card box would be quickly crushed and ruined.
Angles are generally good but the effect is strongest when you’re standing and the audience is seated. If your audience has a view from slightly above, you may flash. For the most part, you’ll want your audience mostly in front of you. One strong aspect of this effect is that the action occurs above the waist. This effect is probably best for close-up and strolling work.
I think that “Empty” is practical as well as worthwhile. But I’m not sure that I would use it in place of David Regal’s “Sudden Deck,” a prop that I have used in the past (click here to read my review). But there’s lots to like and this is no empty promise.
