ELECOMHUGE Trackball Mouse, Wired, Finger-Operated, 8-Button Function, Palm Rest Attached, 52mm Smooth Red Ball Windows11, macOS (M-HT1URBK)

Update (7/13/2023):I purchased an alternative that seemed close in 'stature' to this mouse because I wanted Bluetooth connectivity, as mentioned earlier for my notebook(s) in case I travel. In general I wanted to just use one mouse. The idea is I use it on my PC (using usb dongle) and then BT elsewhere. Anyway, I got a Nulea, which is nice but it still doesn't hold a flame to this mouse. The back of the Nulea is almost slippery compared to the HUGE and is not as wide, thus, it just doesn't feel as comfortable. My hand sort of just wants to slide off the surface, which makes the material they popped on the HUGE pretty thoughtful.Update (5/10/2023):This has remained my absolute favorite mouse. Wear and tear is so very low even though I use it daily. All I can hope for now is that they make an almost identical updated version, but wireless AND Bluetooth and maybe even a plug-in for a wire so I can buy one to use with my notebook(s), basically a Deft Pro version of this mouse. Again, I personally love and highly recommend this device. This is THE PERFECT finger trackball mouse for bigger hands (and even perhaps, for any hands).Initial Review:I'm one of the unfortunate few index trackball addicts. I cannot use a regular mouse for very long and I certainly can't use a regular mouse for any sort of gaming. That being said, what started me on this terrible journey was a Logitech Marble Trackman - that trusty trackball that's still around. Shortly after succumbing to the trackball, I moved on from that to a Logitech Cordless Trackman Optical, this is where things went wrong. It was for me, the perfect device. A trackball mouse that just seemed to fit perfectly in my right hand. It had a few extra buttons that came in handy for games. My first lasted 2 years and the second lasted roughly the same except just before this one died Logitech decided to discontinue the product - oh, %^#t.I went through phases of tech grief, which are sort of similar to regular grief. I denied that the product was discontinued and convinced myself that the product was cycling, which is when they sometimes discontinue the product and re-release it in a few months with different colors or a different name. This did not happen. I then became quite angry, which I know is quite silly but hey, it happened - because I felt betrayed by the company. How can you, as a company, release 1001 different models of the same mouse but just 1 very, very, very basic model to cater to index finger trackball users? I then entered the bargaining phase, which is where the tech part of this comes in. I took to their forum, Twitter, Facebook, anywhere I figured I could nudge the company into getting the idea that we (index finger mouse users) exist, enough so to at least bring another model to market. I came pretty close to publicly begging. After months and not a peep from the company, I became sad - depressed isn't the word I'd use, again, this is not real grief, just tech grief. I felt sad because I felt really uncomfortable and out of place using a regular mouse and nothing else was working for me. I tried several from various companies like Kensington and the thumb trackball from Logitech (which I cannot use, whatsoever). Finally came acceptance. A slap in the face recently is that the company introduced a new thumb trackball, as if their M570 weren't enough, they released the sleek MX Ergo Plus - Ouch. I bought a new Logitech Trackball, the basic one, you know and that was that for some time.Enter Elecom, a foreign company that doesn't seem to be on the radar yet. One day I decided to do another search for trackball mice and I discovered the Deft or EX-G series, whatever they call it. I bought it and it turned out to be a great cordless Trackball, however, the ball never quite felt right and the shape was just off enough to make it, not quite a gamer mouse for me, though I could use it for everyday PCing, etc.Finally, finally, I get what I want/need. They've released a larger version that is, perfect, for what it's worth. I can't really explain how great it feels so I'll say this. I wrote those previous anecdotes for a reason, so you could/can identify with me. If you've ever used that darn Logitech Cordless Optical Trackman OR the Microsoft Trackball Explorer, which is very similar in feel, then this is it, folks, this is the trackball for you.At first, it feels a bit large, too big in fact - but give it a few, just like the Trackball addiction sneaking up on us, the device eventually becomes just right. I don't quite remember how my hand was when I used the previous devices but I think the most jarring difference is that you won't have to contort your ring finger to right-click, as the buttons lay right under your hand in a naturally open position. The top of the device is large and there's soft padding so you literally just lay your hand down on top of it, it's very comfortable. There are some extra buttons that I haven't figured out how to use since I haven't read the manual (3 function buttons) but you get the staple of an advanced Trackball otherwise, you get a clickable scroll wheel in addition to 2 clickable buttons (forward/backward for browsers) just above it. All of these tend to work universally and are easily bindable in games. The left button is under the scroll wheel in a really great position, IMHO, as my thumb sits right there. The 3rd function button lies beside the right clicker. There's a switch on the device that seems to increase trackball speed manually vs. through software.So far, it's a fantastic device. I got the corded version and am seriously considering buying 2 or 3 more and just putting them away, just in case. I'm giving it some time to see what if anything happens to the device after months of use.Thank you Elecom and Thank you seller and Amazon!Just came back to say that after many months, the mouse still works perfectly. I own 2 now. 1 for my main system and another for my work system. I'm going to buy 2 more as I mentioned before to put away, just in case Elecom decides to call it quits on production. I also have my eye on the Bluetooth model that I will likely use with my mobile devices - I'll see. The HUGE is so great, I'm not sure I want to change the formula.

If, like me, you have become somewhat skeptical about exaggerated product claims let me assure you this is THE largest input device I have EVER seen. If you don't have at least XL sized hands, forget about it and get the EX-G or a Kensington or something.To give you some perspective, it is about twice as long and 1.5x as wide as the Elecom EX-G which I also own two of. This is NOT a small or compact device in ANY way. That being said, this isn't a bad thing if, like me, you find most trackballs to be a bit on the small side. Just be prepared to clear at least a square foot of desk space for this big boy.Aside from the size, you get the standard mouse buttons as well as three FN buttons you can remap to do anything you like, from keypress macros to opening apps. You can also remap the regular buttons as well if you wanted to.The Elecom Mouse Assistant is actually the best mouse software I have seen and you really do have complete flexibility to make the trackball behave in the way you want it to. This can be downloaded from the Elecom website. I found it a bit tricky to find the English version of the page but found it in a minute or two. The app also defaults to Japanese the first time you open it but there is an easily visible language menu to switch it to English, Chinese (simplified and traditional), or Korean.If you choose not to install the software, it works fine in plug and play mode and behaves as a normal trackball, the FN buttons just wont do anything until you set them up.It's definitely impressive and I quite like the design. Something to look into if you have large hands, like trackballs, and want to break out of the Logitech/Kensington rut.

I've never used a trackball but wanted one to reduce wrist and shoulder strain from my mouse. I do all sorts of stuff - coding, 2D/3D art and design, digital music... All on a Linux dual monitor setup.Out of the box the mouse worked for me. The trackball felt smooth but I see what they mean about stiction. When the ball is still and you try to make a small adjustment of a few pixels, the ball sticks a little sometimes and then lets go suddenly, making you overshoot your tiny movement. Rubbing the ball with wax paper did help this. The mouse was usable though and I used it as is for a few days, even composing a full song in Ardour, and it was fine.The extra function buttons should be easily bindable to keyboard shortcuts or bash commands especially in X11 environments. Wayland is a little finicky about it but plasma 6 has support for mouse bindings in the settings panel under Wayland.The mouse wheel on mine rolls fairly freely, with little detent. I haven't been able to get the function keys to emulate other mouse buttons yet. YMMV.Ergonomically it feels great to me, though for me an additional wrist rest helps out. Thumb scrolling and left clicking was weird at first but it's becoming normal.Replacing the ruby bearings really did make the trackball better. I used the black ones, they're silicon nitride maybe? And the ball rolls freely with much less stiction. New bearings make the higher dpi modes a lot more practical. It took me maybe 20 or 30 minutes. You have to take the mouse most of the way apart and the little bearings are real tough to manipulate, but it's a doable modification. You'll need a set of precision screwdrivers, a good tray to keep parts on, some bent nose tweezers, a guitar pick or other spudger. Be gentle and patient and use a guide.I'm happy with my purchase all told. Works out of box, replacement bearings make it much sweeter to use.
