*The product comes with a video code and a website. Go to the website and enter the video code before you do anything.* It is not a self working trick nor is it easy. However the variety of amazing effects you can do with this almost undetectable deck switch makes up for it. It comes with a resupply just in case something breaks (I don't want to give away to much information).
It's benefit is that it has a wide variety of truly stunning effects that you can perform. It's downside is that you have to perform the trick quite quickly, making sure not to give it away, and practice is needed to do so. Some will have trouble while it might be easier for others (it may depend on the size of your hands). Anyway, it can be an amazing trick with practice.
