Logitech G700 key features

Although it is designed to be wireless, and communicates to a tiny "nano" USB receiver at a speed of 1,000 reports per second, Logitech also gives you a "quick-connect" cable for recharging your mouse or to use in critical situations where you can't afford losing power or running into the slightest wireless signal interference.
