Mike Cheney's Adsense Videos

I am going to get these:

Michael Cheney's Adsense Videos.

I have heard really good things about them. Like people who have been using Adsense for years watch them and apply what they say and they quadruple their earnings.

I listened to some of his free advices and used it, and already my earnings went up as a direct result.

Comment here if you have experience with these videos or any feedback.
