ELECOM HUGE M-HT1DRBK: Specs, Features, Pros & Cons
ELECOM built the HUGE around a 52 mm ball, larger than anything Logitech or Kensington ships, and then built a memory-foam palm rest behind it so the whole hand can lie on the device. It is a finger-operated trackball: the index and middle fingers roll the ball, the thumb gets the main clicks, the scroll wheel and the back and forward keys. The name is not marketing exaggeration; this is a big, planted object that does not move once it is on the desk.
The design decisions are the interesting part. The ball rides on three artificial ruby bearings that ELECOM deliberately made oversized so dust settles less readily in the seats, and the sensor underneath is a gaming-grade optical unit tuned to the ball's coating. A three-position slider on the body changes the tracking speed between low, mid and high without touching software, and there are eight buttons plus tilt scrolling, ten assignable functions in total through ELECOM's free Mouse Assistant utility.
Power comes from two AA cells rather than a battery pack, and the receiver is a micro dongle that stores inside the body when you carry it. This is the wireless version; ELECOM also sells a wired HUGE under a different code, and a lot of the confusion in reviews comes from mixing the two.
Who is it for? Someone with a large desk and a large hand who wants the wrist supported at all times, and who is happy to use a Japanese-market product with a Japanese manual. Who should be careful? Anyone with small hands, anyone who wants Bluetooth, and left-handers, because the shape is firmly right-handed.
It is also cheaper than the big names, which is why it keeps turning up in recommendations despite the rough edges.

Editor’s note
What I like about the HUGE is that ELECOM solved the real problem with cheap trackballs, which is the bearings. The oversized ruby supports genuinely change how the ball feels compared with the small steel balls on budget units, and because they are large they need cleaning less often. Combined with a ball this size, small cursor moves feel controlled rather than twitchy, which is what a finger-operated design should deliver.
The palm rest is a love-it-or-leave-it feature. If you rest the whole hand while working, it is the most comfortable trackball I know of. If you hover your wrist, the rest just makes the device longer. Try to picture your own posture before buying rather than trusting anyone else's verdict.
The compromises are real. There is no Bluetooth on this variant, only the 2.4 GHz dongle, so it will not pair with a tablet or a locked-down work laptop without a free USB port. The AA cells last a long time in low-energy mode, but you give up the convenience of USB charging, and the mode switch for battery saving is on the underside. ELECOM's software is functional and dated, the documentation is Japanese-first, and warranty handling outside Japan goes through the importer rather than the maker.
Against the Kensington SlimBlade Pro, which is the obvious finger-ball rival on this site, the HUGE wins on comfort and price and loses on connectivity, build polish and the option of using it left-handed. Against the Logitech MX ERGO it is a different kind of device: thumb versus fingers, and the HUGE needs a bigger footprint.
I would buy it for a fixed desk where wrist support matters more than portability, and where a spare USB port is not in short supply. I would skip it for laptops and shared or ambidextrous desks.

The bottom line
The ELECOM HUGE M-HT1DRBK earns a VS Score of 18, trailing most of the 79 mice we compare here, at least on the spec sheet.
- Who it’s for
- Right-handed desk workers with larger hands who want a finger-operated ball and a full palm rest, and who have a spare USB port for the receiver.
- Who should look elsewhere
- Laptop users who need Bluetooth, left-handers, and anyone with small hands; the body is long and the shape is fixed.
- The trade-off that matters
- You get the biggest ball and the most support in the category, but only on a wireless link that needs a dongle and batteries you replace rather than recharge.
- The main alternative
- Kensington SlimBlade Pro Trackball – ambidextrous, adds Bluetooth and wired modes with USB-C charging, at the cost of no palm rest and a higher price.
