Tennis Tutor Tennis Tutor Plus AC/DC w/ 2 Button Remote

If you are looking for a tennis partner that will sharpen your skills, build your confidence, and raise the level of your game, you've just met your match. Tennis Tutor is portable enough to take anywhere, yet powerful enough to challenge even top-level players.
This Tennis Tutor Plus includes all the features of the standard Tennis Tutor, plus adds topspin and underspin capability. A simple dial controls the amount of topspin or underspin you desire. It also includes a two-function wireless remote control. The hand-held remote lets you start and stop ball delivery, and control the side-to-side position of the ball throws. The Tennis Tutor Plus measures eight inches taller than the standard Tennis Tutor.
This model is available with AC/DC capability. That means you can play at your home or school court using AC power, then take the machine with you to a court without an electrical outlet and use it there too. There is no separate battery charger necessary as the machine charges the battery any time it is plugged into a live AC outlet. And it is worry-free since the internal smart charger will always keep your machine ready to play without overcharging the battery.
