ELECOM EX-G Left Handed Trackball Mouse, 2.4 GHz USB Wireless, Ergonomic, Thumb Control, Tracking Roller Ball, 6 Programmable Buttons, Tilt Scroll

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.

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.

Switching from a traditional mouse to a trackball wasn’t easy, but this ELECOM EX-G made the transition much smoother than I expected. It takes a bit of getting used to, but once you adjust, it can actually be quite comfortable and efficient for daily use.This is definitely a budget-friendly option, so don’t expect premium materials — but it’s surprisingly durable and feels well-built for the price. The ergonomic design is great for long hours, and the programmable buttons are a nice touch.One small issue I’ve noticed is that the trackball occasionally feels like it gets stuck or doesn’t roll as smoothly. I’m not sure if that’s just part of the learning curve with trackballs (this is my first one) or a minor flaw in the product. Either way, it hasn’t really interfered with my ability to work.Overall, a solid entry-level trackball mouse that offers good value and functionality once you get past the initial adjustment.
