When I purchase tricks, I tell myself that I am buying the effect, not the method - The effect is
what the audience wants and no matter how simple or silly the method, if it works for them, then the
trick is a success.
That said - I cannot recommend this trick for the price. It is a bit angley
and makes a clicking sound that takes a lot of practice to cover with a snap. The cube cannot be
manipulated the same way a normal cube can.
It is a shame because the effect is so powerful but
the audience will immediately want to rush and inspect the cube but it doesn't start or end clean.
If the creator included a method of cube swapping and a cube with with to swap, I could reconsider
my stance.
