A dedicated DPI button toggles between 750 and 1500 counts, letting you switch from fine pixel work to fast full-screen sweeps without opening a settings panel. Six programmable buttons are remappable through the free ELECOM Mouse Assistant software, downloadable from the ELECOM website, and tilt scrolling adds horizontal movement for wide spreadsheets and timelines.

Frequently Asked Questions
Does the ELECOM EX-G work on a Mac?
Yes. ELECOM lists macOS 10.10 and later as supported, alongside Windows Vista, 7, 8.1, RT8.1, and 10 or later. The Mouse Assistant remapping software is a separate download from the ELECOM website.
How do I change the DPI on this trackball?
A dedicated DPI button on the mouse switches between 750 (LOW) and 1500 (HIGH) counts. No software or driver is needed for the toggle.
Can I remap the six buttons?
Yes. All six buttons are programmable through ELECOM Mouse Assistant, which you download free from the ELECOM NET website. Assignments are made per button in the utility.
How hard is it to clean the ball?
Push the ball out through the hole in the bottom of the housing and wipe it plus the three 2.5mm ruby bearings. The oversized bearings resist dust clogging, so cleaning is needed less often than on small-bearing trackballs.
Is it wireless, and does it need batteries?
No, it is a wired USB trackball, so there are no batteries to replace and no pairing step. It weighs 4.5oz and measures 94.7 x 124.4 x 47.9mm.
