Like it a lot. Even though I must say it's not 100 percent bullet-proof, reason for this is the
"human factor". I guess 99 percent of the times it should work, but the person I showed it to
managed to give me the "wrong" answer anyway, and it wasn't my fault. For those who own it, it went
like this: cat's toy got "shining silver" as a result, because my friend was imagining a balled up
sheet of aluminium-foil, which her cat's like to play with. How high is the chance of this
happening? Very low. But imagine this happens to some performer on TV, meeting the only cats
preferring aluminum balls over what a EVERY decent cat typically plays with.
Also the
instructions are not really clear how this can be performed on the phone. Maybe it can be done, but
then might as well explain how, because obviously things will either get a bit confusing or obvious.
