The Logitech MX700 just raised the bar of expectation on precision and control. With its powerful MX optical engine, the MX700 instantly responds to even your fastest movements. The rechargeable Fast RF cordless technology gives the responsiveness of a corded connection, but without the cord. Our two Cruise Control buttons provide continuous scrolling through long documents or websites. And the rapid charge base station acts as a receiver and a charger in one. You made the demand so we built the device.
