Had to reset and start over with the 30 day challenge due to serious medical issues. Customer support was very helpful and friendly. Now, after just one week, I find myself literally waiting for the sun to rise each day so I can play the guitar without bothering the neighbors in my apartment complex. I love the way Tony's lessons break everything down in simple steps and doesn't overload me. The videos are top quality and I print out the TABs and place them on my music stand. This is going to be a great journey - I can feel it!
