These controllers were made for a left wrist amputee. Any gamer understands that the right hand is the more important because the main action controls are on the right side. This player wanted to have the d-pad moved to the right side to allow his right index finger to access it and also have the left trigger and bumper moved to the right on the underside of the controller. In addition, small extensions were added to the left joystick which raised the contact surface high enough for his left nub to move it easily. The requested modifications were incorporated into XBOX 360 and PS3 controllers giving the user the ability to play games on both platforms.
