Let's start with the positive, the trick is very easy to do. The only part that is even a bit
challenging is catching the card from the air. The double impact of back color and face change is
impressive. There is also a well taught tutorial segment on how to switch out the gimmicked card
that can certainly be employed with other card illusions as well as this one.
On the minus
side, and maybe it is just the one I received as these are hand-made, but the "stuff" that makes the
Bipolar trick work may be obvious to anyone with a keen eye. Some of the visual tells can be hidden
through manipulation, but not all.
The trick loses a couple of stars because of this
drawback.
