The Logitech Wireless Trackball M570 gives you a different kind of comfort. This stable trackball stays in one place and its sculpted shape supports your hand to let you work all day with ease, instead of chasing a mouse around your desk. The tiny Logitech Unifying wireless receiver is small enough to stay in your laptop, and you can use your trackball for up to 18 months between battery changes*. You get precise cursor control wherever you want to use your trackball – hard tables, comfy sofas and lumpy beds are all no problem for your M570. The integrated scroll wheel and easy-to-reach Back/Forward buttons make surfing on a laptop or navigating a home-theatre PC a breeze. * Battery life may vary based on user and computing conditions.
