Vintage Logitech TrackMan Portable Mouse is a trackball mouse designed for portable use. With a classic wired connectivity, this Logitech Trackman model features 3 buttons for precise control. The unit does not come with a charger, and its untested status adds a degree of uncertainty to its functionality. However, with the promise of free shipping, this vintage mouse could make a unique addition to any collection or a reliable replacement for a traditional mouse.
