The European and American versions of the controller do however include circuitry and mounts for a rumble motor, a possible leftover from the Japanese version of the controller, and therefore installing the motor is a simple process. Due to a lack of vibration-compatible games at the time, the European and American versions were not shipped with rumble feedback and, as a result, weigh significantly less than their overseas counterpart, and fall somewhere between the weights of the standard controller and the DualShock. The hand grips are 1.5 centimetres (0.59 in) longer than the original controller and the later DualShock controller.
