Review: works as expected - no complaints (well one minor complaint that seems to have resolved itself) - 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.
Review: Great price for a great mouse! - 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 desertcart 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 desertcart 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 desertcart 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.

## Questions & Answers

**Q: Do you have to use the trackball or will the cursor respond to mouse movement?**
A: If I understand you correctly. The mouse itself is stationary. This is a trackball mouse. The soul use of this is spinning the ball to move the cursor. I am unsure of any hybrid mice with the features you describe tho it made me wonder myself. You can always keep a regular one plugged in next to it.

**Q: Any right handers using it to relieve carpel tunnel and repetitive stress injuries in the right hand (by switching to the left)? If so, feedback??**
A: Been using the Logitech m570 on right hand + standard Logitech wireless mouse on left hand for years. It's helped a lot with wrist pain. Finally decided to try this Elecom left handed trackball as it doesn't seem like Logitech has any intention of making a left handed m570. Might get the right handed Elecom eventually as well.

**Q: what size batteries does it use ?**
A: AA battery × 1 required.

**Q: Will this mouse work with windows 10?**
A: Yes it works great with Windows 10 still having a problem right  scroll wheel 2 move across a row in Excel 2013 worksheet sheet. Very smooth Mouse

### ⭐⭐⭐⭐ Changed my mind and give this a thumbs UP!
*by E***T on 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.
