I took off 1 star because my unit arrived with a short string. This means there is a fair bit of
tension on the string making it quite awkward when using the pen and could lead to a spectator
accidently exposing the method. It's not a huge deal, and it will be relatively easy to install a
longer string. However, for $90 I am a bit annoyed. I would like to have had full confidence with
the pad right out of the box.
Other than that, this is an awesome prop and does as
advertised.
