Yeah, you know how this is done, and yeah, the principle has been used for years now . . . but these
new props--the coins--add a level of professionalism to Free Will. They handle nicely, are
well-made and have heft to them, and they're easy to use. And of course the video tutorial is
great, and covers a LOT of things you may not know about variations of and history about the effect.
Buy this--it's one you'll carry and use.
