Symmetrical gaming mouse for esports. Higher profile. Driverless; plug and play. 3360 sensor. High Profile Design Fit for both palm grip and claw grip users, the high profile design of the ZA series provides more support for your palm and allows movement to feel more stable. For Different Grips Concave curved sides designed to lift the mouse easily. Projected notches on both sides that allow palm grip users to lift the mouse with ease. The upper front curve of the mouse is steeper, giving a larger gap between the fingers and mouse. This means less reliance on the fingers and more for palm grip users. Right-side buttons removed to prevent interference with a right-handed user's grip. With the ZA’s smooth and seamless design, you won’t experience any discomfort related to jagged edges or protrusions made solely for aesthetics. The Humps of Symmetrical Mice Low profile, more space between palm and mouse. High profile, provides more support for your palm. High profile, peak is closer to the middle (compared to ZA), more space between the palm near your wrist and mouse.
