Worthless junk.

This was a complete waste of money and time

### 2/5 — Guide

*2010-02-26*

This is not what I expected. I thought it was going to do the work for me, but actually it only goes over the basics with one to two examples. Don't waste your time and money with this, unless if you want a short lesson on how to do it.
