ELECOM Huge Trackball Mouse, 2.4GHz Wireless, Index Finger Control

This is by far, the best computer input device I have used in over 30 years of programming. And I say this despite a few negatives. That is how good this trackball is. The pros: - The trackball is very large, allowing both rapid movement across the screen and very fine, delicate, movements to move the cursor with great precision. - The scroll wheel is not only adjustable for degree of vertical scrolling, but the wheel can be also moved up and down for horizontal scrolling. Pressing the wheel like a button toggles the page and line scrolling. 5 functions in one wheel. - In addition to the 5 function scroll wheel, there are 7 (more than I have ever seen on this class of device) different buttons so with this device you can perform many different functions. There is software that allows you to set each of the 7 buttons to perform any of several functions, or emulate any key, or any combination of up to 3 keys (like Control Shift K). I set it for Left Click, Right Click, Copy, Insert (Paste), Enter, Delete, and I use one button to call a highly used Macro shortcut key combination. In addition the software allows other settings. - The HUGE (yes that is the name) device is just that. It is brilliantly designed so it fits your right hand (left handers are out of luck) with your wrist on a very soft pad and the trackball and all the buttons are manipulable with your fingers only, No wrist or device movement so the seemingly larger footprint is really the same as or less than the area needed by a mouse. Unlike a mouse however, you do not need a flat or smootth surface for the trackball to rest on. It's fine on a pillow, on youir leg, on the arm of a chair, on a table, on top of a book or newspaper, and can operate at almost any angle. -- I have had very bad luck with wireless input devices as I am very sensitive to the latency time between the movement of the mouse and the movement on the screen. This is not a problem with a USB or otehr wired input defice, but with no wire there is always some latency. The Japanese engineers of this Huge trackball have reduced the latency period so much, that I never even notice it on most movements and it is quite small in the 1 out of 70 or 80 moves where Windows or the Apple OS is adjusting and cleaning up its memory. A first class achievement. There is another problem with most wireless input devices: They are energy hogs. If the battery is not rechargable, you might go through batteries very rapidly and expensively. I almost did not buy this for that reason. This requires 2 AA batteries. I have used mine for over 3 months with the original cheap "no-name" batteries that come with the device. Duracell or other class batieries will last even longer and I cannot yet report on this point, but it cannot be too bad as a pair of batteries will last at least substantially longer than a 3 months. It is important that you use the on-off switch to turn the device off if you are finihsed for a session. I generally turn mine on when I boot up in the morning and do not turn it off until I retire at night -- typically about 14 hours. With that, my batteries have lasted over 3 months, so this is pretty impressive. My great enthusiasm exists despite the following negatives: - The instrcutions are not bad. They are terrible! - The website that you have to go to download the software is also terrible and hard to find your way around. - When you do download the software, it is not intuitive as a Microsoft program would be. So you have to work your way through some trial and error and struggle with the on line instructions. Fortunately it is not that complicated. - I am pretty sophisticated with computers and it took me about 4 hours to finally get the device installed and the software configured. Don't worry at first about how you configure the buttons. Use the factory defaults. Then when you get the hang of it and see how time saving it can be, then play with different configurations of the buttons. The Huge trackball is a little pricey, more than twice what a lower-end, wireless, Logitec mouse costs and about 10 percent more than other upscale devices cost. There are plenty that are more expensive and not as good. But I think that if there was ever a good trade off to pay a little more momey for getting quality and functionality, this is it.

Quick Summary: MSTE users who don't have an MSTE - get this mouse as it's the closest "replacement" to date. Obviously, if one wants a mouse like the MSTE, then get an MSTE. But even a used MSTE costs a bit and you have to be careful of the cord. If one wants something Less Expensive that closely resembles the MSTE and is also cordless, then this is the best mouse on the scene since the MSTE itself. Update2: Trying to add some slightly better pictures and others that show the MS Trackball Explorer, Logitech Cordless Optical Trackmall, and the smaller Elecom "DEFT" trackball mouse. But some pictures are not loading to the site. Sorry. :( Update1: IMPORTANT NOTE: Waaay down in the comments (the oldest one at the "bottom" should be a link to the Elecom software download page and the English PDF manual. As this mouse is "very new" you *DO* need a more recent Elecom proprietary software to recognize this mouse if you wish to use it's three proprietary function buttons (F1-F3). Long Winded Review =============== This new Elecom Fingerball wireless mouse - the M-HT1DRBK - appears to have been released is June 2017 and has been available on Amazon since July 2017. In August I was about to order a second of the smaller Elecom M-DT2DRBKs when I stumbled over this new **larger** "HUGE" mouse and figured it was worth a try. The M-HT1DRBK just arrived and after giving it a ten minute test spin I just ordered two more. No clue if it will take "1-2 months" for the next batch to arrive, or if the price will drop from $85.99, but would say it is certainly worth the investment. FYI: It actually does say "HUGE" on the mouse itself. :) Comparisons to the MSTE (MS Trackball Explorer) ====================================== 1) It has a nice large "red ball" like a certain MSTE we all know and love. In fact, the Elecom ball is slightly BIGGER than the MS one. There were many reviews about the smaller Elecom mouse's "grey ball" having issues, and several people purchased a "blue" M570 ball to swap with the "grey" one. From my quick tryout of this new mouse with it's "red ball", would say that the quality looks to be significantly better than that of the smaller mouse's "grey" one. An excellent improvement. 2) This mouse is *MUCH LARGER* than the smaller "grey ball" M-DT2DRBK. Excellent for people with "larger" (aka normal sized) hands. 3) It is a bit wider than the MSTE, and Elecom moved one of the three proprietary "Function Buttons" to the right side of the ball. If you use their proprietary software, this would give you "two buttons to the right of the ball" just like the MSTE. 4) MOST IMPORTANT OF ALL. This mouse has a PALM REST. As this seems to be an alien concept to most mouse manufacturers I will state it again - this mouse actually has a place for the palm of one's hand to "rest" while using the mouse, so for the first time since the MSTE, there is actually a trackball that not only fit's one's hand, it is actually COMFORTABLE. Plus it doesn't have teeny tiny thumb-killing buttons like a certain L*git*ch Trackman. Wish I could show a decent side-view of the palm rest, but this can also be seen with via the pics on Elecom's web site. 5) ??? I would assume that being a wireless device, there may be an occasional "lag" in response times, but cannot say for certain. However there does appear to be a wired version of this mouse as well. It's part number (August 2017) is M-HT1URBK. Usage ===== Bulk of this review was written after only ten minutes of mouse use, so haven't had the time to give it an extended run, but observations so far are positive. "Weeks later" - Still great. Haven't tried the Elecom software yet myself (not using the F1-F3 buttons). - Seems to respond MUCH better than the smaller Elecom version (blue or grey ball). - Range seems to be about the same as the smaller one. About nine feet out it gets tricky and Line of Sight is critical. - The "left" button isn't as "tall" as the MSTE's, so my clumsy thumb is hitting the wheel, but this should be a minor issue. - ??? I read elsewhere that the "left" and "right" mouse buttons are "better quality" than the other buttons, that one should be able to tell the difference, that they should have made *all" the buttons "better quality", etc. Haven't noticed any difference between buttons yet. Too busy enjoying having a wireless mouse that actually fits the shape of my hand for a change. Customization - aka The Buttons ======================== So far as remapping buttons, "drivers", and support for various operating systems... Would assume this mouse works as a basic mouse in anything from XP up to Win10. You've got your Left, Right, Forward, Back and Wheel Buttons, plus the three Extra Proprietary Function Buttons F1-F3. Remapping the eight buttons and basic customization is where it gets interesting. Would assume one needs at least version 5.1.0 of Elecom's proprietary software to use/control all eight buttons. For now I am sticking with X-Mouse Button Control which allows configuration of everything except the three extra Function Buttons. Both programs allow for the use of multiple profiles for easy customization across different applications. Elecom's software (and English PDF manual) is available from their website. I will try adding possible links as a "comment" later as this review is too long as it is. Odd Future Issue (?) ================ Since the palm-rest is made of a "soft" material vs plastic, I wonder how it might hold up over time. Will it wear out? Time will tell.

The ergonomics of a trackball (or mouse, I suppose, if I ever used them) are very personal. What fits one person may not fit another. For a designer, one solution to this problem is to provide several alternative controls and a way for the user to specify what they do. This seems to be the philosophy behind the 8-button Huge model from Elecom. The Huge trackball is indeed fairly huge, and next to my Logitech M570 it seems unrealistically huge. But in fact it's almost exactly the same size as the Microsoft Explorer trackball I used for many years, until Microsoft inexplicably stopped making them. After a few others, most of which relied on clumsy rolling bars and ball-bearing races, which were rough and unresponsive, the optical trackballs arrived, notably the M570. Reluctantly, I decided perhaps my thumb could be as nimble as my index and ring fingers, and to my surprise it worked fine. I settled on that device for several years, but one problem kept recurring -- the microswitches in Logitech products are beyond cheap. They're very short-lived, at least for someone who makes their living on the computer. I've bought 6 of these compact, effective trackballs, and that's just not acceptable quality. Logitech also makes keyboards, which again, I quite like -- except their keycaps are cheap, with painted-on labeling that wears off in a year or so (the home keys, for those who touch type). A nuisance, but blank keycaps don't make the keyboard useless. Double-clicking button switches do. It was time to try another brand, and I bought an Elecom clone of the M570, and it's held up nicely in my studio, which isn't the friendliest place for precision devices. With the good performance of that trackball, I decided to see if my muscle-memory from the finger-style trackball was still functional, so I got the Huge model for my office. To my great relief, I found that switching back from thumb to forefinger control was effortless, and once the big red globe was sitting next to my K780 keyboard, I found myself unconsciously reaching for the ball with my fingers instead of my thumb. Some will disagree, but although the thumb has a bit more freedom of movement, I believe the forefingers have significantly more refinement of sensitivity and movement, and along with the much larger ball that gives me a very useful level of control. I may not convert to finger models for the four other computers I use regularly, but I suspect I can switch back and forth between thumb and forefinger models without a problem -- most of the others are used to control CNC, laser, MIDI, etc., so the pointing device isn't as critical as it is for Adobe apps and extensive writing. The specific features of the Huge are well documented elsewhere -- the buttons and wheel all work fine. I can't yet say whether the switches will last longer than the M570, but it's hard to imagine they wouldn't! Overall, I give the button action and placement a 90% score. The areas for improvement are few, but worth considering: The wheel is great in its own right, but its placement slightly obstructs the default LEFT button, and I would address this by extending the LEFT button outward a little (I might try sticking a layer of plastic on it myself). More significantly, the wheel is also a button, and in its near horizontal placement it's hard for the thumb to press it all the way to a click without bracing the fingers on the opposite side, to keep the whole device from sliding to the right. This is a problem that could only be fixed by using a much lighter spring on the wheel-switch itself. There is a similar "ease of activation" issue with the slider at the bottom left. This is used to select Low, Medium, or High wheel sensitivity, and although it works as expected, actually sliding it is much too difficult for interactive use. I can "deliberately" put it any position, but it's impossible to just "casually" slide it back and forth while actually using the pointer. That means if you need to change resolution for a moment or two and then return to normal, it's just not doable. Unfortunate, but not a big deal for my use. It would have been nice, though, and it seems odd to provide that capability and not make it effortless to slip into the needed gear. Finally, my biggest disappointment. With the M570, my wrist sits squarely on my desk, so it gets uncomfortable pretty quickly, and I resort to various pads, thick and thin, to avoid stressing that bundle of tendons, nerves, and blood vessels exposed on the bottom of the wrist. The Huge, on the other hand (pun intended), has a large wrist support area with a squashy pad on top -- perfect! Except on my unit the pad is only slightly softer than the tread on an automobile tire. It's definitely a pad, softer than wood, but not by much. If I push with my finger on a thick section (about half an inch thick in places), I can with some force get it to collapse about 1/3 of its thickness. But my wrist is a large area and the weight of my hand & forearm is far too little to produce any compression at all. It might as well be solid plastic (or tempered steel) with a thin cloth glued to it. It's only technically a pad. Realistically, it's not. I do wonder if Elecom might have replacements for the pad, perhaps with some compliance or softness. There's no cushioning value in the present one, and I'm even considering peeling it off (if possible) and replacing it with something that's actually soft. I don't know if Elecom reads these reviews, but they would have no way to contact me anyway, so I'll have to try contacting them elsewhere. My conclusion is that I like the Huge very much, I'm very satisfied with the ball action, there are buttons aplenty for my clicking needs, and with luck it will prove much, much more long-lived than the nice (but flimsy) M570 it replaced. I do recommend it highly, with the small caveats mentioned.

Update: I just purchased my 5th Huge wireless trackball; I have one in my home office, and use three at work in different locations, two that are just a few feet from each other. I love them and 4 of the 5 work exactly as expected. The 5th one was bought used and was likely returned for the same problem I encountered with it, but thought it might be a set up problem on my end...its not, its the trackball. Whenever I plug my laptop into the system that trackball is attached to, I have to unplug and replug the usb transceiver to get it to work. Once its working, I can go all day with it working fine, even if the laptop isn't used for a while and goes to sleep, but once I disconnect the laptop and reconnect it, i have to also disconnect the transceiver and reconnect it to get it to work again. Some other reviews mention that. The other four work perfectly, especially after a week or so of use to 'break them in' to where the ball responds without sticking when first trying to move it. They do break in. My oldest one is a couple of years old now, so I am also happy with durability. I previously bought the huge version and the smaller original deft, both wired. I bought the wireless one I am reviewing about a week ago, as "used--very good". I'm very happy with it; its a keeper, if set up correctly. First, make sure the transceiver is located in a position where there isn't interference of some kind. I originally placed it in the back of a caldigit T3 thunderbolt dock and it was working, but had the slow start and perhaps hard to be precise with like some people have talked about. For various reasons, I replaced that dock with the new Plugable thunderbolt dock, and noticed how poorly my logitech wireless keyboard was working when I placed its transceiver and this trackball transceiver to the back of the plugable dock. I moved both transcievers to a 4-port USB hub so they are still out of the way but not behind objects, and this trackball is now working excellently, with no hesitancy at all. the slow start and imprecision is completely gone--BTW, I have always had it set to the middle position in the back (for precision), and the middle position for speed. It doesn't emit the high pitch hum that came from the small wired deft, and I have found it comfortable to use for hours on end. I downloaded the software ( I am using mac OS Big Sur) and quickly programmed the keys. For me, I have both of the far right keys set to function as a right click just because its less confusing for me to do so. I have the smaller function keys programmed to cut and paste...but it will take me some time to get used to using them for that--I am coming most recently from a logitech trackman that is only 2 button, so I have to rewire my brain to use the extra functionality. Same with the track wheel. It works great, I just have to train myself to use it. I've been using trackballs for 20+ years, and can't get the hang of thumb-balls. If logitech had a more advanced finger driven trackball than the trackman, I probably would have gone that route, but the whole point of moving from the trackman was to go wireless. The new kensington is having mixed reviews and was too pricy to try sight unseen. I'm quite satisfied with how this telecom is working. My use over the past week has included some graphics work where precision is needed, not just documents, spreadsheets, and webpages. Thumbs up. Update July 2021--I must like these because I now have three of these (plus 2 wired ones) for different work stations I work from during a typical week.

I bought this because my older trackball was starting to die on me. I regretted it. For background, I spend a LOT of time on my computer. I use a trackball and an ergonomic keyboard to reduce as much strain as I possibly can. This trackball looked like it would be a great replacement. Maybe for some people, it would be. Perhaps someone with larger hands, this would work better, but my hand is on the smaller side. The buttons are reasonably easy to reach. Only one of them is truly awkward. However, the scroll wheel is located above the button you would normally use for left-click. This tends to make you bump your thumb into the scroll wheel every time you need to use it for a different button (like the two directly above the scroll wheel). More importantly, the placement of the scroll wheel forces you to bend your thumb in really awkward ways to get a smooth scroll (as opposed to a bunch of jerky small scrolls). And what would be a plus - the fact that the buttons are all programmable - becomes a bit less pleasant because the software you use to program those buttons is not well designed, and is very awkward to use. I realize I've used the word "awkward" a lot in this review... and that pretty much sums up my opinion of this trackball. It works, it seems well-made, but it wasn't, in my opinion, well designed. I would not recommend this trackball unless you have already held it in your hand and know that it will work for you.

Hot take. This will be the next PC trend in the wake of RGB lighting and Mechanical keyboards. My wrist thanks me and I feel just as competent gaming with this as I did with my Logitech. Some things I have concluded using Trackballs: - Finger trackballs > Thumb trackballs - You have much more control using your fingers and are provided a larger ball which provides finer control and range of motion. - The experience is akin to combining the best attributes of the trackpad, and the analog stick. - This may sound like a step back but let me explain. An analog stick moves, eases, and stops on a dime. the Trackpad is intuitive, fast and precise, but becomes harder to control when you need to hit a certain pixel point of accuracy. The ball combines the best of both without the drawback - The scroll wheel solution is not entirely perfected... yet - I see several approaches on how to handle the scroll wheel. The first and simplest is keeping the scroll wheel in the usual place if you use a thumb based trackball. This works best but you loose the finger ball advantage I mentioned earlier. So that means you have to come up with something different on the other designs. Kensington Mice have a scroll ring. This is a great idea but has ultimately two underlining problems. First, they patented the daylights out of this. No other brand will be able to use that solution in the name of greed. Second, when gaming the ring can get in the way and cause you to accidentally scroll while gaming if you're not honed in yet. They may pass over time, but I feel it is worth bringing up. In Elecom's case the scroll wheel rests on the thumb AND it tilts for side scrolling too! Ergonomically that makes sense. However if you do a lot of scrolling your thumb will hate you unless you middle click. As a programmer that is not a common luxury for many editors. I work around this by other means, but I would like to share a solution. Simply have a spring load in the scroll wheel so that the scroll wheel behaves like and analog stick. Further back and forth you use the wheel the faster the scroll. This reduces the strain you get from repeated scrolling normally. A simple, but elegant solution. Having listed my overall views on trackballs Let me list my pros and cons to this mouse: Pros: - Fantastic shape, feel and comfort. - Best sensor I have used in any trackball so far. (kensington expert, logitech trackman t-cj12 are the others I have used) - DPI switch is a great tool that I use frequently depending on the application ( I run six monitors so it's great to speed up briefly to move to another monitor and then lower it once I need to get to work in that particular spot. - SO MANY BUTTONS ALL OF WHICH YOU CAN MAP! THANK YOU. cons: - Scroll wheel is better than other similar mice, but still can be improved by making a more fundamental design change (again I strongly suggest substituting with a low profile analog stick instead) - r and fn3 buttons could be better placed. This is the one and only serious blight to this mouse. I have normal sized hands ( read nobody has said to me "hey your hands are Big/Small" ever in my life), and you can clearly see from just the picture itself the buttons are narrow and the mouse itself has lots of unused space they could have used to spread the two out. The followup deft pro mouse Tries to solve this by getting rid of that entirely. I'm guessing because they were trying to make a smaller mouse to accommodate smaller hands, but I personally think the size and shape is just right and only needs to stretch the those two buttons. Having listed all my feedback I am EXTREMELY satisfied with the design, and now am that one weird guy who will tell his friends and family members about how great trackball mice are now. Do yourself a favor and get this mouse.

I’ve owned several trackballs and this one is fantastic. Compared to a Kensington Expert Wireless and an Elecom Deft Pro, this one is a near perfect blend of the two, a larger trackball in an ergonomic form factor. My hand rests well on the pad and the ball is easy to maneuver, at least well enough for my usage as a tech professional. It may not be as nimble as the Deft Pro, but it’s quite luxurious. I expected I might have to do a bearing swap but it was incredibly smooth right out of the box, hard to say if this is luck of the draw or quality control from Elecom has gotten better, but I’ll probably leave it stock for now. The only downside, and this is my fault for not realizing, is that it doesn’t connect over Bluetooth. Having used the Kensington Expert Wireless and Deft Pro I assumed this would have both dongle and Bluetooth capabilities, but alas, it does not. This will make it just annoying enough for traveling into the office that I’ll probably keep using my Deft Pro for travel, which to be fair is a much better form factor for portability anyway. Trying to decide between this and the Deft Pro? The DP relies on your hand laying directly on the desk like a typical mouse. I haven’t found this too bothersome, but if you want a pad, get the Huge. I do find the Deft Pro to be slightly more ergonomic despite not having a pad, but I love the pad on the Huge and since getting it haven’t gone back. If you value portability and want/need Bluetooth connectivity, get the Deft Pro. If your hands are smaller than 7 inches, go with the Deft Pro. Otherwise, give the Huge a shot! Given my complaints around lack of Bluetooth, I didn’t remove stars because it’s my fault for not realizing this in the product description. I still love and use this product daily, but hopefully they make a Huge Pro some day!

I have been searching for a good trackball replacement and wanted to switch from a thumbball to a fingertip ball. The big ball square didn't work for me so I decided to try the Huge. Unfortunately it isn't working out for my thumb and hand. Quality: As for the build and feel of the trackball, it has a good weight and feel to it. It does not move around as I am using it. It looks very durable and would last a long time. I cannot comment on battery life as I have only had it for a short time, but the AA batteries seem to be doing very well even staying on the whole time and being ready when I reboot the computer. Connection: It only has the 2.4ghz dongle and no bluetooth, so the connection was a little spotty when plugged into my usb hub from my Mac Mini. I did get better connection when plugged into the main SSD hub on the bottom with a faster communication speed. Settings and speed: Once connected well, it is very responsive and the mid setting for me was perfect. Value: I think it is a good value for a large trackball. If your hand is very flexible in your thumb, it may work very well for you and the buttons and customization is great. Scrolling: That's where my main issue comes in. When Your hand is on the soft pad and resting near the ball, it is very comfortable, but to actuate the scroll and the button on the scroll, it puts my thumb in an awkward position and I have to reposition to get at it with more accuracy. Once I reposition, the heel of my hand falls off the pad and puts my hand at an angle for the upper buttons. Sadly I may have to return to a thumbball trackball. It did connect well with my Mac Mini and the forward and back buttons worked out of the box. With the Elecom software I was able to customize all the buttons to my liking. Al-in-all, this is another trackball I really wanted to like and be my main input device, but my weird hands will not let me. Hope this was helpful.

Everyday I had a constant pain in my right hand while using normal mouse. With Elecom Huge pain went away. Now my hand stay still and only fingers navigate cursor. I also like high quality Omron switches, clicks are feel really nice and satisfying. Build quality great! General advice for future users. Remove a ball once every week and clean three bearings inside. It’s super easy and take less than a minute. Also when you will get this trackball or after cleaning you might notice that ball doesn’t move smoothly, just roll ball in your hands couple of times. It will get a little grease from your palms and start roll smoothly.

Lo mejor del trackball es la cantidad de botones que tiene (programables) y que el tacto al apoyar la palma es acolchado/gomoso. Se alcanza bien con manos grandes (es mi caso) a todos los botones y a la bola. El botón izdo, que es el que quedaría a la altura del pulgar es para mí algo incómodo de alcanzar/memorizar su posición, pero no mucho. El scroll se alcanza bien una vez tienes cogida la posición con el pulgar para el botón izdo. El botón dcho. también se hace un poco raro, pero hay dos en esa zona, luego puedes tener dos configuraciones diferentes (yo uso el más apartado para "suprimir" o para "cerrar ventana", según la aplicación). Por cierto, mención especial al botón del scroll porque tiene modo "tilt" y esto sí resulta bastante poco común (esto es que le puedes aplicar al scroll movimientos laterales también, vamos izda y dcha). Para ir al grano, si queréis detalles mirad el manual buscando en google 20180405_MSC-M-HT1DR_ALL_ver.1.pdf y si no os habéis cansado podéis seguir leyendo la review. Algo que no me gusta es que el fabricante te dice que desinstales los drivers de otros ratones que puedas tener instalados. Yo tengo varios que quiero seguir usando (como el M570 de Logitech) así que no lo hice, y me toca andar extrayendo e introduciendo de nuevo el pincho usb de este dispositivo en cada reinicio del PC (Windows 10) para que lo detecte (aunque los drivers no hay que volver a instalarlos ni me han dado conflictos). Por cierto, los drivers se descargan desde la página del fabricante a la que se puede llegar escaneando el qr-code de la parte inferior del dispositivo (ver imágenes). Sobre la resolución decir que permite varias velocidades (hasta 1500 dpi) y sensibilidades. Yo le pongo la sensibilidad H (parte inferior ratón, la L es para ahorro energía) y la resolución intermedia de 1000 dpi (en caso de una pantalla en 1080 te irá bien así, si tienes 4K o más pantallas o eres gamer tal vez quieras subirla). Así que ese nivel de personalización que permite adaptarse a diferentes configuraciones (resolución, pantallas, etc.) y usuarios (que vayan a supervelocidad o en modo tortuga) también está muy bien. Sobre la duración de las pilas dependerá de su capacidad y del uso, yo recomiendo ponerle recargables de unos 2500 mAh. para que puedan durar unos meses. La bola se puede extraer para limpiar el interior fácilmente (se introduce el dedo por la parte inferior del ratón y ésta sale haciendo presión, no por la propia gravedad). Hay que limpiar de vez en cuando la zona de alrededor de los rodamientos, pero sin obsesionarse. Los rodamientos podrían ser un poco más finos ya que ofrecen algo de resistencia, no mucha, esto va sobre gustos. En definitiva, un ratón muy original y completo (le sube el precio el tema de la logística desde Japón, así que no lo tendré muy en cuenta en la valoración). Si te gustan los trackballs como a mí es uno de los que merecen la pena tener en la colección.

pratique et ergonomic, Je l’utilise en tant que personne avec handicap J’en suis très content et le réglage de sensibilité de la sphère est vraiment pratique. Bon appuis de la main sur la souris et confortable

PREMESSA: funziona solo in modalità wireless ! (niente cavo, e niente ricarcia via cavo) Per il resto nulla da dire.... è l'huge ! ottimo mouse trakball come che già recensito per la versione cablata (in caso vi invito a leggerla dove ho postato qualche foto) e ora visto la comodità ne ho preso uno wireless per usarlo anche con altri pc ! come al solito , per usarlo con programmi tipo grafica o cad, ho rinunciato alla garanzia l'ho di modificato, sostituendo le sfere originali (testardi alla elecom) con quelle ceramiche, optando per le sfere ceramiche 2.5mm di grado g5 !. Dopo la modifica, il mouse ha cambiato il cosidetto "pelo" (come si usa dire) diventano una periferica top!.

ロジクールのTM-400を愛用して来ましたが、後継品が出ずに嘆いていた者です。 同じ３本指（玉が小さいので2本指ですかね？）タイプのDEFTも購入しましたが、どうにも納得出来ずにいました。 しかしこのHUGEは玉がデカイ！TM-400よりもデカイ！！ 操球感も抜群！メッチャ気持ちいい！！（ポンコツになってしまったTM-400と比べて） そしてカーソルが早い！超早い！デュアルディスプレイの端から端まで一転がし！！（スイッチでいつでも3段階に調整可能） なのに3本の指でボールを保持して細やかに動かすのも自在！！玉に触れてなきゃクリックでカーソルがブレることもない！ 大玉最高！！マウスなんていらんかったんや！！！！ と、本当にべた褒めしたくなる製品です。 右クリックが細長くて押しにくいと書いてらっしゃる方もいますが、私の持ち方だとボールに掛けた薬指の側面で 常時押せるので抜群に具合がいいです。が、形状やボタンの配置が独特な製品なので、店頭で実物を触ってみるのをお勧めします。 残念な点としては、低反発素材のパームレストですかね！？慣れてきたのでそんなに悪く無いかなー、とも思いますが、 DEFTと似たような無難な形状にして、脱着可能なクッションを付けておけば良かったと思います。 あと、スクロールホイールの質感が凄くショボい（ロジクールの無段階～クリック切り替え機能付きのホイールと比べて） のも気になります、が、些細な事はどーでも良いのです！ 親指型しか出さない奴等ではなく、エレコムさんを応援します！！ありがとう！！ 操作に慣れてきたのでマウスアシスタント5もいろいろ触ってみました。 使うソフトウェアごとに操作を割り当てられる上、マウスジェスチャにも対応しており非常に使いやすいです。 私はJWCADで使う時には、進むを中央クリック、戻るをESCにしています。 ホイールを一定回数早回しすることで自動送りが始まる機能も、細かく設定できて悪くないです。 ますます好きになったのでもう1台買い足そうと思います。 追記 結局有線のM-HT1URXBKを2台買い足しました。 余ったこいつは車のドアに脱着出来るように加工してしまいました。 運転席のハンドルに取り付けるテーブルの上にノートPCを置いて、ドアの肘置きに大玉トラックボール! HUGEがあれば図面も車でスイスイ書けてしまいます!! これこそマウスには絶対真似のできない芸当であって、トラックボールの完全勝利と言えましょう!!
