Logitech M570 Wireless Trackball Mouse, Black
Maximize cursor precision with this wireless trackball mouse. The adjustable laser sensor and trackball design offer impressive accuracy, while the contoured shape supports your hand in an ergonomically correct position for lasting comfort. This Logitech mouse offers flexible placement with a 2.4GHz receiver and lasts for up to 18 months on a single AA battery. The Logitech M570 Wireless Trackball Mouse combines fingertip cursor control and a high-definition sensor for comfortable, responsive clicking and scrolling. Instead of moving the mouse around your desk, the ergonomic body stays anchored in one place while you roll the trackball with your fingers to navigate documents and websites. One AA battery powers your cordless trackball mouse for a year and a half, so you don’t have to worry about maintenance.
