I give this product 1 star for 3 reasons. Please do read my review:
1. This is a tech-based
effect when it really doesn't need to be. Why, then, is it? Read on.
2. For carrying such a big
prop and taking lots of pocket space, the effect/result, in my opinion, is not worth it. There are
better ways to reveal important info.
3. The big one: this product looks to me like a blatant
rip-off of Vincent Hedan's Pi effect, which is far superior in every way. The cover is
near-identical. The plot is near-identical. The effect mirrors a key part of the original. It looks
like David Penn liked the original and wanted his own version, made up a vastly inferior method, and
published it with uncanny similarity to the original, especially from a spectator's POV.
Conclusion: don't waste your money with this. If you really like this type of effect, buy Pi Max
and put in the work to perform it.
