It's amazing how much I've used this thing. I perform more than anything else I do. And the best part is that it really doesn't appear to be an effect until you restore the bill.
First, the DVD is very comprehensive and covers every aspect of the stealth pen: It's history, workings, penetrations, restorations, outs, etc. There's also Oz's routine which is just fantastic. At the end of the DVD, there are about 5 full, uncut performances of Oz blowing people away with this routine. The whole thing is packaged in a very cool looking, thick DVD case that houses the pens.
The basic effect itself is fairly easy to get down. Also, audience response on this thing is incredible. The fact that it's THEIR money makes the effect so much more shocking. The expressions you'll get from the ripping sequence are just priceless, especially when you reveal that the bill is restored. And, if you're worried about people questioning the pen, DON'T. Almost every time I've done this, people just want to see their dollar. If they do ask for the pen, there's an incredibly easy way to clean up naturally and hand it out to be examined.
Others have mentioned quality was an issue. This was one of the things I was worried about. The pens aren't fine writing instruments but they're pretty decent quality and hold up well. They look like normal, everyday BIC pens. The gimmick also works great and I love the idea behind it. It allows you to perform the illusion super close-up to people while still looking legitimate.
One evening, I left the pen in "writable-mode" on the coffee table while some people were over. Someone even picked up the pen and used it to write down a phone number without noticing a thing (like they should. the pen looks completely normal). Then someone mentioned if anyone had seen the new bills. I immediately thought to myself "Yes! Perfect performance opportunity!". He took out his own bill to show everyone. I now had the perfect situation to perform so I started saying how apparently there's this new security feature that is only found on the newer bills. I asked if anyone had a pen. "Here's one!". Perfect. Threw in some more patter and BAM pen was through the dollar. Got a few "Hey!" 's and "Wow that's nice of you" 's. The illusion is completely convincing. As magicians, we tend to think this is an impressive part of the effect. It's not. At this point, the audience believes that you actually stabbed their bill and will probably pretty confused or pissed off. I got a bunch of gasps when I ripped out the pen and restored it. They grabbed at the bill amazed and confused without even asking for the pen. I cleaned up the pen and set it down but no one even asked to see it. Everyone was talking about it the whole night.
I love this so much because of how practical it is and how easy it is to do at the drop of a hat. I bring it EVERYWHERE and have gotten so much mileage out of it.
Overall, if you don't buy this for the steal of a price that it is, you're missing out. So do yourself a favor, stop reconsidering, debating, and changing your mind and buy the d@mn thing already.
