Nice tutorial for the newbies, however I recommend anyone new to SQLi to do it manually and learn how to do it that way. After you know how to do it, and can do it efficiently manually you can use a automated software. By doing it manually first you will have the knowledge to fix any hiccups the software encounters, and if it can't get through, you can always go back and do it manually to figure out the issue.

Agreed. You probably stated it in the most respectful way possible.
