Stop chasing a mouse around. Your trackball stays in one place and puts control under your thumb, so you don’t have to move your arm to move your cursor. And its sculpted shape supports your hand for comfortable control all day long.
This trackball includes the Logitech Unifying receiver. The tiny wireless receiver stays in your laptop, so there’s no need to unplug it when you move around. Plus, you can easily add a compatible keyboard, Number pad or mouse-without the hassle of multiple USB receivers.
