A new product called a Bat Brain does the same thing. It is 1/3 the cost and comes with a CD and grip guide and balls. Much more fun. It attaches to your with a taper fit in seconds and creates a flat edge. This means more to the swing than grip and hand position. Palm /palm position forces the batter to lead and continue hip turn in front of the hands. I actively promote Jacks products almost daily so maybe he will post the www.swingbuster.com site for you to see it.
