Not sure if i am missing something here but as a working magician i am astounded by the reviews for this although they all seem to be extremely short.Strange that. Firstly, the method for forcing the card is nowhere near foolproof and will definitely not work every time. A b/c would be better but again that is hit and miss if the spectator cuts the cards.
Secondly the work needed to be done with the other box is difficult to say the least and to keep from flashing the method would be difficult. An M Case would be perfect for this though that will cost £30. All in all this is not great and not practical for close up.

This was very easy to figure out because i do lots of card magic. I still think the idea was really nice. I still purchased this anyway.

This is an incredible trick in general, not to mention the effect can be used for many different things! You can even use a borrowed deck!

Clever, easy to perform, so you can play with a presentation

This is the esiest prediction i have ever seen

This is one of those effects that really take you by surprise in terms of the simplicity of the idea matched with a brilliant execution.

Excellent gimmick and used often. great reactions

Good card trick , the method surprised me!!!!!!

I really like this trick because it's really easy to do

This is one for the ages and should be in everyone's repertoire
