AOpen O-75B is an ambidextrous three-button optical wheel mouse that plugs into a USB or PS/2 port through an adapter. The O-75B comes with a racketing wheel centralized between the two button keys. The wheel may be moved slowly in incremental ratchets, or quickly with a single, sweeping motion of the finger to rapidly advance through multiple ratchets. The wheel also functions as a third button when it is activated by pressing on it. The O-75B has a simple and elegant design with its contoured body ensuring the user's comfort. This high precision mouse glides across most surfaces, recording motion optically without a ball or rollers.
