I bought this effect to add to my repertoire of "street-magic." This is a direct, visual, and safe effect that fits perfectly into a busking routine. I have seen others perform this effect, and when it's performed correctly it attracts a crowd. Although Justin goes through everything that you need to know, I personally have never been able to get the method to work reliably every time. This has deterred me from putting it into my act; however, others have had great success with this effect. The price is very reasonable and both the instruction and production quality of the dvd are good - so if you are at all interested in this routine, then you should buy it. At worst, it is an investment that will only add to your knowledge. At best, this could become an excellent opening routine.
