The ad copy pretty much tips the method, so I'll be a little more open than I normally might, when discussing the method. First, watch the trailer. What you see is what you get. There are no funky cuts to hide the method. It's totally legit.
Production quality is top notch: clear explanations, good lighting, excellent close up shots, clean editing, etc., etc., etc. The only thing that was a bit of a bummer was that the entire teaching is done with text on the screen. It was sometimes a bit hard to keep up with the text and watch the footage at the same time. Other than that, I have absolutely no issues with the DVD quality and your the ability of the viewing magi to learn the effect.
In my mind, a product like this comes down to one major thing: how well made/easy to use is the gimmick. In this case: Check!
Don't get me wrong; you'll definitely need to get in tune with your gimmick and spend some pretty heavy time practicing, but once you've put the work and time in, you've got a killer effect that you can do pretty much anytime and anywhere, as long as you have your cap with you and there's a bottle of Aquafina (or similar bottle) kickin' around, you're good to go.
The gimmick will definitely withstand a casual inspection. In the trailer, you saw Luke Dancy hand the bottle out to a spectator who removed the lid, dumped out the water and then replaced the lid. You'll have problem with that because they have no idea what's coming. However, after the penetration is over, there is likely to be much more of a desire to really closely examine the cap. Depending on how well your gimmick locked after you perform the effect, you may be taking a minor risk here.
However, there are plenty of different handling techniques that increase the liklihood that your gimmick is truly (and safely) locked in place. Just make sure you're very familiar with how your particular gimmick looks and works - I imagine that each gimmick is a little bit different.
Finally, you'll be taught several handling pointers and presentational ideas. By far and away, the best handling is Sean Fields's handling. It looks like you're really seeing everything . . . including the top of the lid at the very last second of the penetration, and you don't have to lock the gimmick because it's already done at that point.
Considering that you get a locking cap gimmick, an extra locking "thingie", 5 normal "duplicate" bottle caps (in case you do want to do a switch and let them keep it) and a well made instructional DVD, and more . . . how can I NOT recommend this, especially at the asking price of $40 bucks.
Final Verdict:
5 Stars with a Stone Status of GEM!
