Cons
- ✗ Wired-only: the USB cable rules out clean cordless setups

- ✗ Trackballs carry a retraining period after years of a standard mouse
Manufacturer description
The ELECOM EX-G wired trackball mouse moves your cursor with a thumb-operated ball instead of your whole arm, so your wrist and forearm stay planted while you work. The EX-G (Exact Grip) shell is shaped to spread contact across the palm and reduce wrist and hand stress during long sessions in creative software, spreadsheets, browsers, or games. An optical sensor reads the roller ball for precise tracking, and five programmable buttons plus tilt scroll let you map shortcuts and pan sideways through wide timelines and spreadsheets without reaching for the keyboard. Connection is plain USB…

Frequently Asked Questions
Does the ELECOM EX-G trackball work with a Mac?
Yes. It connects over standard USB to PC and Mac systems with a USB port. Programmable-button software support varies by OS, so check the product listing for current driver details.
Is this trackball wireless or does it need a cable?
It is wired only. The USB cable supplies power and data, which means no batteries to replace, no charging, and no wireless receiver to misplace.

The body measures 3.7 inches wide by 4.9 inches long by 1.9 inches tall and weighs 5.3 ounces, so it takes up less desk space than most full-size mice.
