I've benefited so often from the reviews on this site I decided to take the first leap for a change
but now I've learned my lesson.
For those unfamiliar with lie detector routines this could
be worth a peek (for half the price) but I'd recommend looking at some of the great routines that
have been well reviewed on the subject.
I was impressed at the length of the instructional
video - until I started watching. It's more of a Q&A / interview style repeatedly going over the
same information. The method is summed up five minutes and the rest is repeating most of the same
information without structure.
