* Important: This gamepad uses an internally-supported stick design, where the stop point is inside the mechanism rather than at the outer opening around the stick shaft. Because of this, clip-bracket asymmetry testing can introduce significant measurement error. That is why the inner blue asymmetry circle has blurred edges and should be treated as an approximate indicator.
