Manufacturer description

The ELECOM DEFT PRO trackball mouse (M-DPT1MRXBK) replaces wrist-dragging with thumb-free fingertip control, letting you steer the cursor across a wide desktop or a multi-monitor retro workstation without moving your hand. Its red index-finger ball rides on three 2.5mm artificial ruby bearings, a deliberately oversized bearing spec that resists dust clogging and keeps the roll smooth between cleanings. When you do want to clean it, the ball pops out through a hole in the base -- no tools, no disassembly. A dedicated DPI button cycles 500, 1000, and 1500 count on the fly, so you can slow down…

SpecPicks Verdict

SpecPicks scored ELECOM DEFT PRO Trackball Mouse using a rating × review-volume × price-fit model applied to published specs and reviews across the keyboards & mice category. エレコム(ELECOM)'s keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How do I connect the ELECOM DEFT PRO to my computer?

It supports three connection types: wired USB, 2.4GHz wireless, and Bluetooth. You can pick whichever suits the machine, which makes it practical to move between a desktop and a laptop.

Can I change what the buttons do?

Yes. All 8 buttons are assignable using ELECOM Mouse Assistant, which you download free from the ELECOM NET website. It is not preinstalled, so plan on installing it before remapping.

What DPI settings does it offer?

Three: 500, 1000, and 1500 count, switched with a dedicated DPI button on the device. You do not need software open to change between them.

Is it hard to clean the trackball?

No. The ball rests on three 2.5mm artificial ruby bearings and pops free when you push it through the hole in the bottom of the housing. The large bearing size also means dust builds up more slowly than on smaller-bearing trackballs.

Does it work with Windows 11 and macOS?

Yes. ELECOM lists Windows 8, 10, and 11 or later, plus macOS 10.13 or later. One caveat: horizontal scrolling does not function under Windows RT8.1.
