- Customization: Utilize the ATK HUB Web Driver to fine-tune DPI stages, button assignments, and macro settings to match your gaming style and preferences.
- Grip Style: The ATK U2 mouse is designed for both prone grip and claw grip styles, with bilateral waist and triangle fixed features for comfort. Experiment to find the most comfortable and effective grip for you.
- Firmware MAX: For models supporting the "Shark Competition Firmware MAX" (U2Pro, U2ProMax, U2Ultra, U2 Master Edition), ensure it is enabled in wired mode for the absolute best performance.
