I love paragon 3D. I think the illusion ist perfect and the teaching as with all of Jon Allens
products is exellent. The method needs some practice. This is not a trick you can do after a few
minutes. If you like the trick with the playing card you will need to practice even more, because of
the slights needed. I also use the clarity box. DavidĀ“s method is easier to do and the box is more
visual for stage.
I recommend both products. The reactions are great.
