Just like the wireless one here (I have two of them)** A: Yes but I have to change batteries every 3 months also, I have to press the right button which is for enter all the way down to the bottom. I don't like it. I will replace it as soon as I can find a reliable one. **Q: If I program this mouse on one computer on one computer and then use it on another computer with the programming saved?** A: To my knowledge you cannot 'program' this mouse. You can configure it, such as button function, but that is done on the computer via the driver settings. If you moved the trackball to another computer, those settings would have to be done done again. **Q: Is the red ball the red ball, the newer more accurate replacement ball, or just simply colored red? Sorry if I missed it in the prior answers. Thanks!** A: It says in the product description that current optical recognition technology is more accurate with the red ball. **Q: How long battery last** A: I never turn the switch on the underside of the mouse off. I use this every day for work (7-10 hours). Lasts 2-3 months easily. I don't feel like I have to change batteries often at all. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works as expected - no complaints (well one minor complaint that seems to have resolved itself) *by on Reviewed in the United States April 19, 2024* 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 guessOverall: 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. ### ⭐⭐⭐⭐⭐ Almost perfect, tho nothing can ever be absolutely perfect *by on Reviewed in the United States January 22, 2021* 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 controlButtons are light to the touch and very quiet, both are wonderful attributes6 programmable buttons! I'm in heavenTwo DPI settings, great to best adjust for a variety of tasksHigh/Low power setting, I expect this will significantly prolong battery lifeSettings software is in English and is intuitive to useErgonomics fit me like a gloveCost was less than half what I paid years ago for my last LogitechCon's....Ergonomically I would have preferred another 15 degrees of tilt, but that's just meMouse Assistant software needs to be DL'd, I had to search for the linkBe sure to also DL the separate PDF manualThis is the biggie.... Other mouse control software must be deleted prior to installIn my case it was just a pain, but not a problem... for other folks, I dunnoComment:I never found trackballs useful for active gaming, only ok for static games like Solitaire and SherlockWhy 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 retrainSearching Amazon only yielded this one brand with a left hand trackball, it looked suitable in every respectI take others reviews and opinions with a huge grain of salt and can afford a few bucks to reach my ownShould I find faults in the future, I will come revise this reviewBut this is made in Japan and not China, so I expect the bestNow 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! ### ⭐⭐⭐⭐ Changed my mind and give this a thumbs UP! *by on Reviewed in the United States May 6, 2024* 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. ## Frequently Bought Together - ELECOM EX-G Left Handed Trackball Mouse, 2.4 GHz USB Wireless, Ergonomic, Thumb Control, Tracking Roller Ball, 6 Programmable Buttons, Tilt Scroll - Logitech Lift Left Vertical Ergonomic Mouse, Left-handed, Wireless, Bluetooth or Logi Bolt USB, Quiet clicks, 4 buttons, compatible with Windows/macOS/iPadOS, Laptop, PC - Graphite - Logitech Signature M650 L Left Wireless Mouse - For Large Sized Left Hands, 2-Year Battery, Silent Clicks, Customizable Side Buttons, Bluetooth, for PC/Mac/Multi-Device/Chromebook - Graphite --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/231772934-elecom-ex-g-left-handed-thumb-control-trackball-mouse-wireless](https://www.desertcart.hk/products/231772934-elecom-ex-g-left-handed-thumb-control-trackball-mouse-wireless) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-25*
