Review: Elecom M-HT1DRBK “HUGE” — creamy-smooth, ultra-customisable multifunction ergonomic trackball - Don’t be put off by the reviews on this page, which at first sight are horrifying news for anyone considering buying the Elecom M-HT1DRBK “HUGE” wireless trackball. A third of the purchasers found it unsatisfactory or barely good enough (up to three stars). There clearly is or was once a quality control problem with the artificial ruby bearings for the trackball. On the other hand, two thirds of the buyers are extremely satisfied or even ecstatic, and there is no problem returning an item to desertcart. Besides, the cure for the bearing problem is known, cheap, safe and quick, a ten minute job with a screwdriver and instructions freely available on YouTube. In addition, the choice of solid large, multifunctional trackball mice is basically this Elecom or its sister, the Elecom EX-G Pro, which is built with the same upmarket components, including the ruby bearings. I decided to take the small risk. My Elecom HUGE is one of the good ones (or later ones, if it was a batch problem, now solved), with a creamy-smooth action on the trackball, feather light switches, one heavier switch just where I want it, and a slight stiction on the scroll-wheel which adds to the precision. You’ll see I gave five stars, so count me among the happy customers. If a finer grading were available, my rating would be 4-3/4 stars because one of the switches is too light for it to be ergonomic in that position — for me. Also, the mostly plain black styling with just the big metallic red trackball (diameter 52mm!) and a smidgin of chrome on the scroll-wheel, while intricate and extravagantly curved, in the eyes of an artist like me should have been further relieved of its blackness. So the quarter-star deduction is for personal ergonomic preferences and to mark an overdose of Japanese “professional” styling, a.k.a. too much bloody matt black, not fundamental faults. Obviously, I consider the Elecom HUGE good value for money; the nearest comparable Kensington costs twice as much and offers less. The HUGE is solidly built and feels like quality in the hand. I wonder, however, whether the self-skinned soft polypad which adds so much to the comfort of operating the HUGE will last the decade or more of hard use the rest of the trackball seems good for. (If the memory foam skin does wear while the trackball survives, I’ll glue on tan leather cut to shape.) The ergonomics are excellent, with large, huge and massive buttons, and would suit a hand of any size, including very large hands. The hand is spread across the big expanse of the aptly-named HUGE, with the thumb operating three of the buttons plus the four-function scroll wheel, including yet another button function, which I instantly allocated to the left click because it is heavier and louder than the other switches, in the instance of the left click a very good thing. An ergonomic error — for me anyway — was making one of the assignable buttons, the piano key under my little finger, as light as the others. The little finger is just not as controllable as the other fingers. In fairness, it must be said that the designer apparently intended the ring finger to operate this button, with the little finger being unallocated. I therefore assigned no function to this button. As a result I control the ball with my two middle fingers, which is another big win in precision, especially since the HUGE offers three resolutions (500, 1000, 1500dpi) selectable on-the-fly with a slider button under the thumb, so that you can make pixel-perfect adjustments on any size of screen, useful in making fine art or graphic design, indispensable in engineering work, and even in typing or editing when the cursor needs to be placed precisely but quickly every few seconds. I’ve also reassigned the default left-click thumb button to the Mac’s COMMAND modifier key (the propeller) because it is too easy to press such a large, responsive switch and get unwanted results if a direct action is assigned to it. This trackball is so customisable and feature-rich, it reminds me of nothing so much as a puppy eager to please. A word about the control assignment software: The earlier software has been rewritten and repackaged, including into English, and is now excellent, regardless of what you may read in the reviews here. It is easy to make the basic button assignments, and you can even use the trackball for gestures, similar to gestures on Apple’s Magic Mouse or Magic Trackpad. Counting the scroll-wheel’s click and tilt functions as buttons, there are ten buttons, which with the variations and the gesture programmer give no fewer than 160 possible functions. It is well worth spending some time reading the help files for the function allocation software accessible through the software dialogue box. For those with much more intricate needs (games players, perhaps?) I’ve also tested the HUGE with USB-Overdrive aftermarket peripheral management software (free with advertising, $20 without), which is potentially more powerful than Elecom’s free software, but only if you know what you’re doing. On the whole, I think most buyers of the HUGE will find Elecom’s layman-friendly software serves them well. So who is the Elecom M-HT1DRBK “HUGE” wireless trackball recommended for? I’m a writer, an editor, a typographer, an industrial designer, and a painter both in traditional media and digitally. In each of those avocations by itself Elecom’s HUGE would be worth the money and considerably more to me, so for each of them the trackball adds far more convenience than the trivial cost per job. Music and video editing, which I occasionally do, also uses the same facilities and speedy precision. The question isn’t really whether the HUGE is great value for money, but whether each individual buyer would get on better with the HUGE layout of the trackball on top and the scroll-wheel at the side, or with the reverse layout of the sister EX-G PRO, which has the scroll-wheel on top and the trackball at the side, which when you change over to the trackball is a straight transition from the common Microsoft-style mice with a consequent shorter learning curve. Personally, I think the trackball on top with the scroll-wheel on the side, as in the HUGE, offers the best ergonomics — and the learning curve was anyway pretty short. The Elecom M-HT1DRBK “HUGE” is definitely recommended.
Review: A seriously good trackball mouse 👍 - I do not normally do reviews, but for this item it is different, so please excuse the essay.. I previously used, quite happily for a number of years a trackball moise that was "thumb driven". I was very happy with it until it decided to expire a few weeks ago. Having seen that there were now index finger driven trackball mice, i thought this is a good idea, may also be more accurate as well. I did my research, and purchased highly recommended and reviewed mouse from a competing manufacturer, and after a couple of days returned it as it was huge, and I mean "huge", and button placement for left and right mouse buttons was not great. So, did some more reseach and came across the Deft Pro from Elecom. All the reviews i saw said great mouse but bad instructions, so i thought how bad can they be? and ordered one. The box arrived next day, Iook the mouse out, looked at the manual and saw it was in Japanese. I also noticed a very small slip of paper tucked in the box, in English advising go to Elecom's website to download the manual in pdf format in English, as well as other languages. I did so, read the manual and the setup was nice and easy, with no additional drivers needed, unless you need to use the additional software, which I do not need at present. So, mouse connected to laptop, and on use found left and right button placement is near perfect. Scrolling the ball is precise and tight, also is very smooth. Would i buy one again? Hopefully the build quality, which feels lightweight but sturdy, will last a few years, so at the time I may need to replace it, I would definately purchase it again. A quick note to the Manufacturer..... Please add a non Japanese manual in the box or a larger note in other languages advising where the instructions can be found, which is the only reason this is a 4 star review and not a 5 star review. I look forward to (hopefully) using this for many years to come.

### ⭐⭐⭐⭐⭐ Brilliant!
*by J***S on 11 October 2025*

I have used several wireless trackball devices over the years, in search of one that ticks all the boxes for me and this is by far the best one I've used. I love it. It is actually massive, so the embossed 'HUGE' is very apt! My hands are big and it's perfect for me. Extremely comfortable, and the default button functions are great. I haven't tried the app to assign the f buttons and don't think I need to, but good to know the option is there if I need it or want to try a different layout. Only improvements would be to make it a rechargeable device, but I'm being picky! Highly recommended!
