Magic Tricks

This is pretty disappointing. It is very obviously mathematical, and rather easy to backtrack and most moderately intelligent viewers will see it as add something, subtract the same thing and bingo, there's what you started with. Tori's attempts at disguise are pretty poor - "there are four seasons in a year and twelve months in a year so go ahead and add four hundred and twelve to your number" ...please! Or "Pisces is a water sign, and there are five letters to spell water, so add five to your number."
The idea of getting an age from a birthsign is a good idea - but the presentation must be subtle. If you buy this you will need to come up with a much better cover story than Tori offers. Normally the main value of a download is in the routine rather than the secret. This certainly isn't true here. And if you just want the secret then simply watch the trailer twice, then think.
There is a bonus, a pdf by Dee Christopher, which offers keywords for the Zodiac signs and suggestions for their use in a short cold reading to give purpose to this trick. This bonus pdf is good, valuable information if you are a beginner mentalist. Buy it for this.
Also read the other reviews. One reviewer suggests that this can be used as a lead into a Magic Square which reveals the Age. Brilliant! That is the way I intend to go.
So with that reviewer's generous freebie and the Dee Christopher bonus I think you can justify buying this just to confirm the details.
