This is the automatic table tennis trainer operated via a remote control that helps players fine tune their game without frequent interruptions to change settings. Similar to a tennis ball machine, the unit’s wireless remote controls lets you change speed, spin, side-to-side oscillation, and serving frequency on the fly. The trainer’s two-wheel design delivers a natural ball trajectory while also allowing players to apply backspin, topspin, and a challenging heavy topspin for realistic practice. The trainer holds 100 balls and delivers up to 90 balls per minute. A memory feature stores your favorite practice settings. Sets up on a standard table tennis top and is powered by the included AC adapter. Balls and paddles not included. Assembly required. Ages 10 and up. 19" H x 10" W x 10" D. (5 lbs.)
