Linkin Sport Tennis Trainer Rebound Baseboard Self Tennis Training Tool Ball Back Training Gear with 2 String Balls

Excercise

I used it in my backyard without having to go to the park, i could just practice in the back yard the harder you hit the ball the faster it came back if you want a more challenging ball to hit.

I like the concept, great exercise.. but the ball is cheap and it busted within one hour of play.... Where to buy a more durable practice ball??
