The Hall Effect joysticks are detachable and can be adjusted for height. To adjust, gently twist the joystick 45 degrees and pull to remove. You can then re-insert it at a different angle to change its height:
- Standard Height (9mm): For fast shooting and general gameplay.
- Increased Height (10mm): For more precise control in games requiring fine movements.
6.3 Full Mecha-tactile Buttons
Experience the responsiveness of e-sports level mechanical buttons. The D-pad uses a tactile switch, while the ABXY and bumper buttons utilize micro switches, providing a crisp, instantaneous feel and lightning-fast response times.

The controller is equipped with RGB light strips that can be customized. To adjust the lighting, use a combination of the 'C' key and joystick operations. You can cycle through 3 light modes: Breathing, Colorful, and Off, and also adjust brightness and color combinations.
