Spinshot-Player is the most advanced battery operated portable tennis ball machine in the world. Revolutionary design can customize your drills and program height, direction, spin, speed for each of 6 sequential shot and then save that into your personalized drill. Easy programming, you can make 2-line drill at any width and any height. You can make vertical oscillation with combined horizontal oscillation, or whatever oscillation mode you want to play with.
According to me...
The spinshot player is everything I have been looking for in a machine. I am a 4.5 player looking to improve my groundstrokes.
With the spinshot player, I am able to program drills that alternate backhands with forehands, as well as change the speed, height, and spin of the ball.
The iphone app makes the setup very easy and user friendly.
I have been very satisfied with the purchase of this machine and use it to practice several times a week. I no longer need a hitting partner to help me improve my game.
