Manufacturer description
The ELECOM EX-G Pro (M-XPT1MRXBK) is a thumb-operated trackball built for people who want cursor control without moving their whole arm. You get three ways to connect it: wired USB, 2.4GHz wireless, and Bluetooth, so one device can sit between a desktop, a laptop, and a Mac without re-pairing every time you switch. The optical sensor runs at 500, 1000, or 1500 DPI, switchable from a button on the shell, which lets you drop to a slow crawl for pixel work and jump back up for spanning a wide monitor. Eight buttons are remappable through ELECOM Mouse Assistant, a free download from ELECOM's…
