ELECOM HUGE PLUS: Features and Differences from the Old HUGE

Published

Introduction

ELECOM HUGE PLUS (M-HT1MR) was announced in November 2025 as the first refresh of the HUGE series in eight years. It is a large trackball rolled with the index or middle finger, with a 52mm ball. This article goes through the specs from KeyLab DB and official information, the differences from the old HUGE, and who it suits.

For a comparison against other index-finger and multi-finger trackballs, see the seven-model comparison.

Differences from the old HUGE

The older HUGE comes as the wireless M-HT1DR and the wired M-HT1UR. Side by side, using KeyLab DB values:

The ball size and body (114.7 × 181.9 × 57.2mm) are the same. What changed is the ball support, silent buttons, connectivity and power. "10" versus "8" buttons may be counted differently, so the numbers alone do not rank the models.

On the bearing, Lifehacker Japan says it uses a high-performance bearing from MinebeaMitsumi. How the ball rolls feels different to different people, so this article does not call either better.

Who it suits

A good fit

  • People who want a big ball and to rest their hand on the body
  • People who switch between several PCs and tablets over Bluetooth (up to 3)
  • People who want quieter clicks (silent buttons)
  • People who would rather not replace batteries (rechargeable)

Not a good fit

  • People who want to carry it. At 181.9mm deep and 279g, it is built to stay on a desk.
  • People who want battery power. It is rechargeable only (older models use batteries or USB power).
  • People with small hands who find a large body awkward. Try it in person if you can.
