Logitech M570 Wireless Trackball Computer Mouse Right-Hand Dark Gray USED New Listing 56156 Port / left RockerItem Details Not typically an item we sell, but for a few years I used a trackball when I did not have ample room on my desk for a regular mouse. I used the larger trackman for a few years before I tried this style briefly. I used this for maybe a week before I went back to a regular mouse and this particular unit went into storage at that time. Includes the USB Reciever and a new battery.
