Basic FormThe black body of the Microsoft basic optical mouse is molded to fit easily in either hand, making it ideal for large offices that would otherwise need special left-handed requirements. Its narrow midsection and flared ends promote a more ergonomical grip.Universal CompatibilityThe Microsoft basic optical mouse dispenses with the batteries and unreliable connections of a wireless mouse, and just plugs right into your computer. It can interface through a USB port, making it a one-size-fits-all solution for setting up your office.Optical SensorThe sophisticated optical laser sensor of the Microsoft basic optical mouse will pick up on even the subtlest movement, translating it to your screen at a precise 800 dpi resolution. This lets you put your cursor exactly where you need it, exactly when you need it, without noticeable lag between input and output.
