does anyone here own the Syned Soy Box. The premise looks great. They say the spectator can examine the deck (and that you can use any deck you want) and they can examine the box.
Now I already have a great theme in mind for this trick but I'm just not sure if it's worth the money (around 180 euros or 160 pounds).
here is a little desciption:
A small wooden box is handed to a spectator. The spectator opens the box and removes its contents - A small prediction envelope a deck of cards. The prediction envelope is opened and it contains one single playing card which is placed face down on the table. The spectator cuts the deck at any place and turns the cut at card face up. The prediction card on the table is turned face-up and it matches the freely cut at card. This is one of the most revolutionary and diabolical effects ever created. The box can be examined and the deck of cards is unprepared and only one prediction envelope is used

The name is different but it's the same trick.
