This video is simply poorly done. It's like he got the neighborhood camera buff to tape his lessons and found out he could sell bunches and make lots of money off of them. Sound quality stinks and video techniques are thirty years old. Meyers knows tennis and it is a shame he didn't employ modern video technology and graphics to improve the value. Forty bucks is a rip off for such a poor product. I would like to return these tapes if I can
