Designed specifically for web browsing, the mouse allows high-precision scrolling to make it easier to read posts on Facebook, shop more conveniently on Amazon, and browse through Google search results even faster. And with the scroll wheel, you can navigate forward and backward the web with ease. * This mouse is based on the world's best-selling curved shape** for a particularly comfortable grip. And thanks to the comfortable shape and the soft rubberized grips, the mouse sits comfortably in the palm of your hand even during prolonged use. With a battery life of up to 18 months*** you can almost forget the thought of annoying battery changes. The intelligent energy-saving mode protects the batteries and the battery level indicator prevents unpleasant surprises. The tiny Logitech Unifying Nano receiver can stay plugged into the notebook constantly. So it's guaranteed not to be lost and you enjoy a reliable connection with virtually no delays or interference. The same receiver also allows you to easily connect more compatible wireless mice and keyboards. Whether at home, school or at work, forget the tiring finger acrobatics on your notebook's touchpad. Enjoy precise click and point functions when surfing the web thanks to Logitech Advanced Optical Tracking.
