Avon Futures Circuit, Professional Tennis Instructor
"As a player and teaching pro, there is no doubt that repetition is the key to good strokes. Ball machines are the best way to groove your ground strokes. To groove a good serve, you need a basket of balls and a target. My students improve much faster when they use the Acebuilder target. It is large, bright yellow and doesn't need to be reset when you hit it. Because they improve so much faster, I now recommend that all my students, from beginner to college players, incorporate an Acebuilder into their daily practice routine."
