I'm finding the videos to be very helpful for myself. Keep in mind that I'm a 13 handicap and have been doing some things very wrong for over 20 years. Just recently have I decided to learn to swing the club properly.
Some things that the videos have helped me immensely with are the grip (I was far too snug and aligned way off), my takeaway, my alignment, head posititon etc..
I like the way that he breaks down each element. It may not be perfect but it certainly is helpful and I cannot afford a professional instructor.
My ball striking is 100% better than it has ever been and I'm just getting started with the videos. My goal is to get to single digit handicap by the end of the season and I'm well on my way.
YMMV!
