Learn Hacking using Backtrack 5 (Udemy.com)

I have used Backtrack before, but after this course I feel like I have miss a lot :), now I am not. It is well organized with real examples. I will recommend this to anyone on an IT Related Job.

This is the 3rd course I bought from Udemy. This is complete waste of money. The instructor shows some examples, but nothing works and he simply exit the tool he used for showing the hacking demo. He talks about many tools, but he just opens it, and just talk about one or 2 functionality of the tool in general. He dont even talk about how a hacker can use it. Majority of the time he is trying to find out the IP address of his host system he is trying to attack (by the way nothing works). He discovers some machines in the network and then says that he cannot attack those as it is not ethical. I understand that the course is just 20$, but still I expect some value. All the information he mentioned in the course is freely available in youtube. You can just read the headings in the course content and just search in youtube, so that you dont spend 20$ for this course. I really dont understand how the instructor can put such a bad course for sale. I am trying to see whether I can ask my money back and buy a 200$ course which has lot of great ratings.
