If your focus is having fun and improving your tennis game with an affordable battery-operated tennis ball machine, the Elite One is by far the perfect choice! The machine boasts advanced features such as full corner-to-corner random oscillation to help you work on your forehands and backhands, up to 60 degree lobs to practice your overheads – a feature not available on any other ball machine, speeds of up to 80 miles per hour to improve your reaction time and heavy top and back spin choices to perfect your ability to return whatever shot comes your way. The full corner-to-corner sweep of the Elite Model 1 has the ability to challenge a wide range of players from advanced to beginners alike. Designed for maximum durability, its 19kg ergonomic design and oversized-wheels allow for ease of transport, even with a full hopper of 150 balls. A 4 to 8 hour battery helps ensure a lot of court time between recharges.
