I read the "Masters" part of the website to know who are you going to learn from and honestly those things they relate seem to be BS, speacially the second guy. But who am I to invalidate someone else's experiences?
As Gerard said above, use your common sense.
Edit: And remember, everyone can make fake testimonials to sell their products online, I studied marketing and you won't believe how deep this goes, it's like, everywhere. Hard to trust these testimonials nowadays.
