"This machine has a few problem. The most serious is that the sensor on the left side ball lock is not working. When a ball get up there, the machine does not sense it, and will go through several ball searches, still can not find it, and finally send out another ball to help, but it just mess up the whole game.
Other problems include the action button will launch the ball (while selecting patches), the metal piece on the left ramp will block the ball coming down from the upper play field, the rubbers on both flippers are very worn out and almost broke. " Guns N' Roses (LE)
