Query: good introduction, but not much of expert knowledge

The "gimics" part of this DVD is the more interesting part, which actually tells you how real card shark cheat with gimics such as various types of card clips. But the sleights bit is a bit too common if you have background knowledge on manipulations such as the pass and differenet types of partial or full control false shuffle, false deal etc. Overall this worth 4 stars as a basic introduction, but 2 stars for those who have prior knowledge on card magic and manipulations.
