Review on Introducing the Game-Changing Eye Coach by Billie Jean King: Revolutionizing the Industry by Robert Pierce

Extremely durable. I have used this with my trainer before and was intrigued by the ability to use it at home. Easy to assemble and I use it with the Babolat Play racket which has a computer chip for shot analysis and feedback. The Coach Pro seems to build the desired muscle memory for topspin forehand. Useful and likely to continue to be useful. Excellent value for money and quality. I ride my bike around the squares so it doesn't seem very portable to me - too big and cumbersome to take apart - maybe it can be carried around in the car.
