ELECOM EX-G Left Handed Thumb Control Trackball Mouse Wireless M-XT4DRBK-G

I got this because I can't use my right arm for awhile and I wanted a mouse I could hold in my left hand standing up. It's not really designed for that but it works. I hands are medium/large. I've been using this mouse for a few days and the design is great. It fits my hand nicely and all of the buttons are easy to reach from adjacent fingers. Today I installed the software to program the buttons and the only issue I had was that it was all in Japanese despite the installer saying that it's for English. But weirdly enough, I just uninstalled it, restarted my computer, and then reinstalled it without doing anything differently and now it's in English. Whatever I guess. You can program the buttons for preselected functions or "arbitrary" ones. Arbitrary ones allow you to add custom key combinations, like Ctrl+W, which closes Chrome tabs. The only thing you can't change is the scrolling of the mouse wheel is only for scrolling - I thought to change it to up and down the volume, but I don't think that's possible. One cool thing about this mouse is that you have right-click, left-click, and then further-left-click, or I guess the left-click is actually middle, but that's confusing. The track ball works well enough, but it's not exactly "oiled" as one other reviewer said. It doesn't get stuck or anything, but if you try to move it slowly while the mouse is a certain angles, it won't go smoothly. This is mostly a non-issue - you just get used to it and forget about it once you do. I actually enjoy using the ball with my left thumb. It's very accurate to flicking the mouse cursor across the screen, or maybe my left thumb is just better than I expected it to be, considering I'm right-handed. Not sure about that, but in any case, I enjoy how the ball tracks. It has a nice weighty feel to it and it's a pretty red color like a Honey Buzzard's eye. Pros: I'm a computer guy and I like everything about it even though the track ball is not perfect, it's good enough and accurate and I enjoy using it, so I forgive. Cons: Not sure why the settings software decided to be Japanese the first time, but I just reinstalled it, literally did the exact same steps, and then it was English.. so whatever I guess Overall: I'm happy with this mouse. It's a sharp looking design, works as expected with an extra-left-click I didn't know I needed, and at $35 dollars it's money well spent.

Rcvd today, earlier than expected, and have been using for a few hours now. The Pro's first.... Ball moves smooth as if oiled, precise and easy to control Buttons are light to the touch and very quiet, both are wonderful attributes 6 programmable buttons! I'm in heaven Two DPI settings, great to best adjust for a variety of tasks High/Low power setting, I expect this will significantly prolong battery life Settings software is in English and is intuitive to use Ergonomics fit me like a glove Cost was less than half what I paid years ago for my last Logitech Con's.... Ergonomically I would have preferred another 15 degrees of tilt, but that's just me Mouse Assistant software needs to be DL'd, I had to search for the link Be sure to also DL the separate PDF manual This is the biggie.... Other mouse control software must be deleted prior to install In my case it was just a pain, but not a problem... for other folks, I dunno Comment: I never found trackballs useful for active gaming, only ok for static games like Solitaire and Sherlock Why I choose this trackball: 25+ years of addiction to my Logitech trackballs on the right while using standard mice on the left (yes, two handed but not ambi) on everything from spreadsheets to drafting to you-name-it has left me not knowing any other way to work. When I permanently wrecked my right thumb, I went to using an ergo mouse on that side, but it just was not the same and I really needed a trackball to functionally get my work done; I'm too old to retrain Searching Amazon only yielded this one brand with a left hand trackball, it looked suitable in every respect I take others reviews and opinions with a huge grain of salt and can afford a few bucks to reach my own Should I find faults in the future, I will come revise this review But this is made in Japan and not China, so I expect the best Now I have this Elecom trackball on my left, programmed to my needs, and an Adloko ergonomic mouse on the right, and I am back in business. There was no learning curve for a ball on the left, I took to it as if I'd had always had one there. I would recommend this trackball to anyone who works left handed! Update June 18, 2021.......... Why did I never have a left hand trackball before? Wow, my work and play just fly along with this trackball and mouse arrangement! The ball moves smooth as silk and the buttons are so joyfully stress free to tap. The extra programable buttons are absolutely the perfect tools for speeding up one's work flow. Despite the negative reviews I saw before purchasing it, there has been not a whiff of a problem. If you need/want a left hand track ball.... get this one ASAP!

2ND Update ========= After tweaking the mouse settings (turning on "Enhance Precision" in the windows settings) and figuring out the "DPI" switch on the mouse, it behaves pretty well. There is still just a slight "catch" in the roller. I pop it out and clean it. Overall, a solid product for lefties. I'd actually give it 4.5 stars at this point, if I could. UPDATE TO ORIGINAL REVIEW ======================== I’ve made a few changes to how I used the mouse and these slight changes have made a significant difference. 1. On the mouse, there is a two position switch under the middle wheel. Setting this to the “Down” position is the “Slow” tracking setting for the big thumb ball. This seems to be important as it gives better fine control, like when you’re hovering over something you have to be directly over to click on. 2. In the software driver (you have to download and install it) I’ve set the “Mouse pointer speed” to the 8th notch. This seems to give a good compromise between moving quickly across multiple screens and precision movement over an object on the screen you have to be dead on to interact with. It’s still NOT as good as a “logiTech” rollerball mouse, but it’s MUCH better than I had originally experienced out of the box. 3. Whatever the issue was with the rollerball feeling like it was catching on something seems to have diminished with further use. Don’t know if whatever it was has been “worn down”, but the movement has become a bit smoother. All and all, it’s enough to move my original review from 3 stars to 4. I still wouldn't use this for something that requires a great deal of precision when interacting with objects on the screen, but for me, it's now working well enough for me to not constantly be thinking that it's not doing what I want it to do. ORIGINAL REVIEW =============== I am right handed, but run my mouse with my left hand, and recently it became necessary to run the mouse from a recliner (due to work from home) and I needed the mouse to be moved using a thumb rollerball. Overall, this seems to be a good product, and it will probably pass for MOST people needing a left handed mouse, but for me it falls just a bit short. That being said, I'll probably keep using it. Here is the list of issues: 1. I usually set my mouse speed to just about the highest speed you can set it too, as I have 5 very large monitors stacked and side by side and need to cover a lot of real estate with minimum movements when moving the mouse from monitor to monitor. Setting the mouse speed this way, even with LogiTech mice, makes the movement twitchy, but the movement is smooth. The movement of this rollerball feels like it very subtly "clicks" when it moves, like its being hung up on something at regular intervals. This results in a slightly "jerky" motion that makes it hard to precisely position the cursor on the screen. It doesn't make it "impossible", just more difficult than it should be. If you pop out the mouse ball, you can see where there are 3 prominent "bumps" (and 3 less prominent bumps) in the interior socket. I'd guess these things are what the mouse ball is actually riding inside the socket and the things that need to have much less rolling resistance to make the overall action of the ball much smoother. 2. There's a 3rd button that your "ring finger" would run. This button's action is disabled by default. It might just be me, but I tend to "click" this button when rolling the ball; so, if this button was enabled, I'd be constantly clicking it. Since it's disabled, it doesn't bother me, but just something to be aware of. Again, overall, it’s probably fine for most people, particularly if you don’t have the mouse’s speed cranked up to the very highest end of the tracking speed.

When it comes to mouse don't go cheap and track ball is the way to go. I had previous numb and painful finger and arm from conventional mouse so I switched to trackball starting with Elecom Huge right hand trackball. I liked that trackball and that was my first experience with Elecom brand. Elecom is a Japanese brand but made in China. The Japanese sure knows how to design quality things. With so much use of the Huge trackball i start having numbness and arm painful again so I decide to get the left side trackball. I bought Amazon warehouse type as i always did. Never disappointed with price saving and it is just good as new without the fancy package. I am not left handed so it takes a bit to get used to while releasing my right hand to rest. I trade full time so i am on the computer a lot looking at charts. A good quality trackball is a must. Logitech does not make left hand track ball so really a good quality one at a great price can only be Elecom. I am sold with Elecom track ball quality and functionality. It has everything I need or want and the quality is just as good as Logitech at way lower price. Search for review you will find many others agree with me. I can attest to Elecom track ball is a great quality one at a great price because i have two now one for left hand and one for right hand. Both for under $60 Amazon Warehouse price. Look just like new when received without the fancy new package. I could not care less about package as long as it works!!!!! There are some complaints about too small. Not true as i have a big hands and it fits comfortably just fine. Now the left side Elecom is a thumb style with smaller ball than the Elecom right side one which is the Kensington brand style trackball with biggest ball and using middle and index finger to roll around. They both work great although i prefer the big ball style. Bottom line is a quality brand (unknown to US buyers) at an excellent low price to match with high quality products. Typically Japanese style. Elecom is a well known brand in Asia but NOT in US. However more people starts to find this out. I only know about Elecom with last year purchase of the Elecom Huge one and was not sure. However with Amazon excellent return policy what is better than buy and see for myself. To me Logitech and Kensington are overpriced; sure they are nice and dandy. I don't need nice and dandy. I just need reasonable quality trackball at a reasonable price for my heavy use. Heck i can buy two Elecom trackballs for even cheaper than just one Logitech or Kensington trackball. Kensington wireless trackball is the most costly. I would not use anything NOT wireless for the sake of convenience and portability nowadays. Don't go for the cheap quality mouse and keyboard even for light use. Quality products make using the computer more pleasantly and comfortably. Well worth their price. With heavy use buying a good mouse and keyboard is a must!!!!!!!!!! Your finger and arm will thank you for it. I am sold on Elecom trackball and will continue to buy this brand for a long time to come.

USB receiver is under the battery. I missed it on the first order and thought it was missing from the open box. Great trackball with switches to adjust power setting and one to adjust resolution. Quality made.

I purchased this as I am ambidextrous. I can use the roller ball mouse with my left hand while typing with my right hand. Basically I am right hand dominate, but I find using a right hand rollerball/mouse more difficult. I like this unit, except it really eats batteries. About 1 per 2 weeks. my right hand roller ball (Logitech) lasts several months. This is my second or third purchase of this mouse,.... so it hasn't lasted as long as the logitech, but logitech does not make a left handed one. UPDATE My Third one just died. Not only did this one eat batteries, I have not had one last more than a year. My logitech (Right Hand) which I use not quite as much, depending on what I am doing is more than 5 years old. THis was my last Purchase of ELECOM products...

I got this for my wife who doesn’t have use of her right hand. Using her computer has been a struggle since she lost it. This makes it much better. For the price, this trackball punches way above its weight. It’s not as customizable as some but it has enough customization to be useful without being overwhelmingly complicated. Tracking is smooth and constant and the ball can be easily removed with one hand for cleaning. The buttons have a nice click and don’t feel cheap or fragile. She loves it.

Probably fine except I couldn’t load the software onto my corporate computer.

Me encantó el mouse su velocidad y respuesta al principio el puntero lo perdía de lo rápido que es pero encontré un botón en la parte inferior para regular la velocidad baje la velocidad pero después me dí cuenta que ponerlo en rápido es mejor hoy día ya tengo más dominio sobre el. Lo recomiendo al 1000%

Mi primer ratón de ordenador fue parecido a este, con una bola similar, que te permitía hacer casi todo con ella. Ahora, después de perder la movilidad de la mano derecha tras un ictus, vuelvo a tener un ratón fantástico para mí izquierda. Cómodo e intuitivo.

Ottimo, lo consiglio

well its a trackball. aka mouse to many. it serves its intended purpose. . the thumb-trackball is well placed. and the additional buttons are well placed, for me t lease. I have been using this lefty tracky ball for a while now. 5 years i would say. This is my 4th purchase, replaced both home and work use. you dont get the writs and thumb fatigue that you normally with normal mouse or center positioned track ball. The reliability is approximately 2-3 year before the buttons get less tactile or begins to hyper shoot. But then again i am a CAD user, and i click & scroll way too much than the average Joe or Jill. oh the custom so far that it provides is fantastic. multi-profile capable. good for many every day software. especially excel or even general copy, paste & enter. :}

Helps to spread the load when using mice heavily. It's helping to manage my shoulder overload, by regular swapping left & right
