Multi Twist was designed especially for beginning pickleball/tennis players. Its compact size and easy operation make it an ideal first ball machine for kids just starting pickleball/tennis. If a child can swing a paddle/racquet, he or she can play with Multi Twist. Multi Twist is simple to use. Just turn it on and it shoots a ball every five seconds. The ball toss can be adjusted from 12 to 20 feet. The unique spiral design holds up to 28 balls. The AC powered Multi Twist simply plugs in to your AC outlet for continuous play. Multi Twist’s adjustable range makes it practical for use in driveways, backyards, and even basements. And since it weighs just 11 lbs, it’s easily transported to the local tennis courts or park. The high-impact plastic case comes with a convenient built-in carrying handle.
