This is a fantastic idea for whoever created it, and something that a lot of magicians get started with when they first start out magic for 3 reasons.

-It's VERY cheap.

This effect is super effective but ONLY 8 dollars for a prop that will last you for YEARS.

-EFFECTIVE!

People freak out. This is a trick that people are familiar with and have seen David Blaine do on TV. This is something people really enjoy and can NEVER figure out.

-EASY!

This effect is one of the easiest effects you can do. There is ONE simple move and that is IT to perform this great effect. This move is taught well in the booklet/page that comes with it.

I really enjoy this effect, even now, years after I bought it and can't reccomend it enough to those who don't have it.

This is one all-time classic. The effect is marvelous and can be done with almost no sleight of hand. Definitely takes a few minutes to check out all the angles and work out your routine, but the time spent is well worth it. I've seen other coin bite versions and I like the Roy Keuppers version the best - very well manufactured and comes with, uh, shall I say extra supplies to make sure it's operating just like new.

Get this awesome, inexpensive trick, practice your routine, and if you find people who haven't seen it in person or on TV, show em - they'll love it!
