Think twice before signing up with this company, especially annual "Hessfest" events. They are expensive, and come with a no refund policy, no matter the circumstance(s). Once they get your money, kiss it goodbye. Customer retention/goodwill? None! Just plain arrogance. Lots of other options available on the internet. "Practice Generator" is crap. Lessons are hyped up as the best on line. Not in my experience. "Become Unstopable" is crap as well. Once you open an account with them, expect a barrage of weekly emails, all with the purpose of selling you more of their crap.
