Side by side, using KeyLab DB values: | Item | HUGE PLUS (M-HT1MR) | HUGE (M-HT1DR, wireless) | HUGE (M-HT1UR, wired) | | -------------- | --------------------------------------------- | ------------------------ | --------------------- | | Ball | 52mm | 52mm | 52mm | | Ball support | Bearing | Ruby | Ruby | | Weight | 279g (without receiver) | 260g (without batteries) | 268g (with cable) | | Buttons | 10 (incl. wheel and tilt) | 8 (incl. wheel button) | 8 (same) | | Silent buttons | Yes | — | — | | Connectivity | Wired + 2.4GHz + Bluetooth | 2.4GHz | Wired | | Power | Rechargeable | 2 × AA | USB powered | | Supported OS | Win / Mac / ChromeOS / iPadOS / iOS / Android | Win / Mac | Win / Mac | 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. ## Related [7 Index-Finger and Multi-Finger Trackballs Compared](https://www.keylabdb.com/en/blog/index-finger-trackballs-compared) puts HUGE PLUS next to ELECOM's DEFT PRO and bitra and models from Kensington and SANWA SUPPLY.
