To put it simply - it's is much too easy for spectators to figure out. I had hoped for much more
than what I witnessed in the sales video but, unfortunately, no.
That and the use of a cell
phone can take away from the 'magic' and point to the phone technology as the amazing prop.
Can it be used for walkabout.... sure. Most definitely not a reputation maker but more of a
quiet filler when you get a little bored.
