If you have to buy only one of two then go for the raven... with it many effects in the trailer of
the bat can be performed with the raven.
The bat is noisy for vanishes. (Except for a
dime?)
If you buy it dont keep the raven and bat at the same place. Maybe I'm imagining
things but the ring effect seems harder to produce since I kept them at the same place for some
time.
Buy the bat if you want to performe telekinetic effects or that penny standing one on
top of the other. Don't buy it if you solely plan to use it to vanish coins with your hands.
Morover the bat is a strong tool. Use it cautiously. It is also a versatile tool if you take the
time to use it not in the most obvious way. Buy Alexander De Cova's 3 DVDs called Treasures for more
ideas.
As I said about the raven, this item's range of use can be widened with PK Putty
available at penguin magic at a very reasonable price.
