I recently had the pleasure to see this item performed in Sao Paulo, Brazil and I'm glad I did. I remember other models in the past we sold for $400-$500 that were bigger and required a long and cumbersome tray. Even then it was limited to certain thin glasses.
This new model is the essence of technology, smaller and more powerful. It's very well built and will last for years. Works with practically any drinking glass. I witnessed it five times to see if there was ANY way I could catch a trace of the hammer - IMPOSSIBLE. Also the way it can be performed either in a card case or cigarette case (it comes with two sizers to allow for the adjustment), makes it much more versatile. It's worth every penny!
This product was sold out at Blackpool Magic Convention 2005 (the largest magic convention in the world). Magician takes a goblet (can be borrowed), puts it on top of a card case and both on top of another goblet. After a few seconds...SMASH! The goblet on top breaks into pieces! The electronic device can be placed into a cigarette pack, a book, etc. Electronic Crasher is a smashing trick! ...It´s a real cracker! Now you don’t need a table to perform this miracle! Leave this amusing illusion just into your pocket!
