The medium S1 Mouse from BenQ ZOWIE is a right-handed mouse with a 3360 sensor designed to be used with an e-Sports gaming monitor. It has a short overall length allowing you to wrap around and hold the mouse. Space between the palm and back edge of the mouse allows for free vertical movement. The front ends of the mouse have been raised to provide palm grip users more space to place the 4th finger. In addition, the side buttons on the right side have been removed to prevent interference with a right-handed user's grip. The mouse cable attachment point is raised at an angle to lower the chance of the cable dragging on the mousepad.
