It's easy to work with if you're willing to put the time into it. It's definitely not something that you can just strap on and perform with right away. If you want to vanish large items like the beer bottle in the trailer, then I would actually advise using a hanky to vanish it otherwise you WILL flash. I think Jim put up the beer bottle vanish just to show how strong the gimmick is. This gimmick is actually ideal for items no larger than a cellphone. However, Jim and Adam (who are awesome to talk to by the way) are developing a topit made to use with the Gecko and a DVD with more trick ideas and other accessories to maximize the Gecko.
