Finally, a “tireless table tennis opponent who will put up with your smack-talking and won’t drink your beer.” The iPong is a portable practice partner that will keep firing serves at you until you call match point. You choose the speed—from gentle to blistering—and the iPong starts spitting balls your way with underspin, topspin, or heavy topspin. The device can serve more than 100 balls before needing to be reloaded, helping you develop new skills fast. The iPong can’t engage you in a rally or pick up any of the 100 balls you’ll hit back. But think of picking up the balls as extra exercise.
