It also supports up to five onboard memory profiles. Dual-Mode Scroll Wheel: The scroll wheel has been redesigned to be lighter and more stable, allowing users to switch between two modes: Hyper-fast free spin: For smooth, rapid scrolling through long pages or inventory lists. Precise ratcheting mode: For controlled, click-by-click scrolling during gameplay. Adjustable DPI-Shift Button: Located near the thumb, this button allows for quick, on-the-fly sensitivity changes. It can be reversed to bring it closer to your thumb or replaced with an included cover to suit different grip styles. PTFE Feet: The mouse features low-friction PTFE feet for a smooth, consistent glide on various surfaces. Connectivity: It is a wired-only mouse, connecting via a USB-A cable. It does not have RGB lighting, which is a feature on the wireless G502 X PLUS variant. Compatibility: It is compatible with Windows 10 or later and macOS 10.14 or later operating systems.
