Empire Reloader B Feeds 22+ balls per second Sound activated - no problems with dark shell paint. Also able to work through ball breaks in the hopper, which, in the past would interfere with the eye sensor. Auto turn off allows you to conserve power and the low battery LED indicates when to change batteries. Able to work with 6AA or optional 4 AA batteries. The board adjusts the power to the motor depending on the batteries used. The 4 AA makes for a lighter hopper. The Rip Drive is a manual feed mechanism perfectly suited for any player who wants to have a backup system in case the loader's force feed system goes down or the batteries die. It also allows you to unjam paint, preload balls at the chrono without turning your loader on and by rotating the Rip drive in reverse you can easily unload the hopper.
