Very robust and high-quality ball machine, very easy to handle: the ball collecting net can be fixed onto the robot without any difficulty. The simple utilisation and the rolling construction allow an easy handling. A remote control for speed and ball frequency can be put on the player’s side. The different ball cuts, topspin possibilities as well as the length of the balls and the oscillator for the change of direction enable best training possibilities. There are only very few pieces that need replacement. They are all replaceable.
