EASE OF USE Tennis Twist is simple to use, just turn it on and it shoots a ball every five seconds. The arc of the ball can be adjusted anywhere from 12 to 20 feet in length. The unique spiral design holds up to 28 balls. Tennis Twist is available in AC and battery-powered models. The Battery Model will operate up to ten hours on six "D" size batteries (not included). Tennis 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. A high-impact plastic case comes with a convenient built-in carrying handle. But don't ask a kid about the convenience of Tennis Twist, they'll just tell you much fun it is. NOT JUST FOR TENNIS Tennis Twist can also be used to toss batting practice for beginning players (using tennis balls). Tennis balls are safer for kids, and won't break windows like baseballs. NOT JUST FOR KIDS Beginning tennis players of any age will benefit from Tennis Twist. Tennis Twist won't mind if you're a little wild while experimenting with your strokes. And dogs that like playing fetch will like Tennis Twist too. WARRANTY Tennis Twist is backed by a one-year warranty covering both parts and labor. SPECIFICATIONS Ball capacity 28 Balls Max.
