The high-end design of the HP Wireless Mouse X4000 mimics the motion of a fast sports car. But the fun doesn’t stop there. This comfortable mouse also features wireless connectivity, 30-month battery life and a highly-precise laser sensor. The HP Wireless Mouse X4000 with Laser Sensor in deep Black features a Link 5 USB receiver that can be shared among five HP accessories. Connect your laptop or desktop to keyboards and other mice without using software or taking up all of your PC’s USB ports. With 2.4GHz wireless technology, you can use your mouse from farther away with less interference. The sculpted and striking lines of this beautifully designed wireless mouse feature smooth edges and sweeping contours for exquisite comfort. Its high-precision laser sensor (1600 dpi) works on almost every surface. And you’ll be alerted when the battery runs low by an LED indicator light. The HP Wireless Mobile Mouse uses two AA batteries.
