EX-G Wired Trackball Mouse, Ergonomic Thumb Control, Smooth Tracking Roller Ball, 5 Programmable Buttons, Tilt Scroll, Computer Mice for PC Mac

Great product and really very useful. Purchased on recommendation and it is well deserved. Very comfortable to use and great range of buttons to stream line working. Grip is comfortable for fairly large hands and ball fall right under thumb for accurate scrolling. Great value for money

Brilliant

Pros: Great software for custom shortcuts/buttons. Nice plastic body. Multiple buttons for customisation. Easy to manage sensitivity. Stock sensitivity is perfect on high. Easy sensitivity switch allows changing to low if precision is needed. Cons: little bit too small, but better than too big (which was a problem with the Perixx wired trackball) Ok: Trackball stutters a little. Much better than the Perixx. Others have praised Logitech as having no stutter - perhaps I will buy one of their trackballs and try putting it in. UPDATE: The June 2018 update to their software (5.16) has mostly broken the mouse, especially arbitrary key function - one must instead use an older version of the software (5.03).

Like many, I came to this after years of M570 use. My 3rd one had just pooped out, I was cheesed off with paying through the nose for something with such a short lifespan, and to be frank, this was the cheaper than the M570 that was on one day delivery (with decent reviews as well), I needed ASAP for work. I'd over looked this one because I thought the buttons being one piece with the hand rest would be a problem, thinking that they may suffer plastic fatigue and snap away, but having now felt the things, I feel they're going to be absolutely fine - only time will tell! On every setting, the trackball is super responsive, a roll of the ball that would have moved the cursor an inch on the M570 sends it flying across the screen, so it's taken a couple of days to get used to, but I do appreciate the strain that is being taken off my thumb! The shape seems ideal for my hand - the curve is just right, and noticeably more comfortable than my Logitech predecessor, but I know that that will be subjective as things like hand size vary wildly. The build is solid, which again, I wasn't getting with my previous trackball mouse. I think the one down side I have experienced so far was that I was expecting the receiver to be stowed in the small storage area on the underneath of the mouse, meaning when I first opened the box, I was cursing up a storm, thinking it had either dropped out when I opened the box, or it hadn't been included, which considering I needed a functional mouse ASAP and didn't want the brouhaha of sending the one I had back (which would have also completely negated the purpose of buying one). Just as I was repackaging to send back, I dropped the plastic display box, where underneath the batteries there was just visible through the white plastic was the tiny receiver, hidden away having been missed due to the plastic being quite opaque. It sounds ridiculous to have been as elated as I was to see that little nubbin hidden away in there, but I really, really, REALLY needed to get working. It speaks well towards the mouse in general that the worst gripe I have so far is something to do with the packaging. It's early doors still, but on the whole I am extremely pleased with how well this holds up in comparison to ye olde M570.

The best thing about this trackball mouse is the packaging. The tracking of the pointer using the ball on power save mode jumps all over the place. On high speed its way too high speed and on super high, which is a combination of the high speed on the trackball base and the high speed switch just below the scroll wheel; oh, that works OK for up and down but I never got a chance to test horizontal scrolling. Where did I get to? Oh yes. The Super high speed. Well, if you can follow your mouse pointer on this setting, you're a better person than me. There is a light, if you want to stand up and put your head over the top of the scroll wheel, which tells you the speed setting you're on. The software, which you need to download, is good for one thing and one thing only. And that's the programming of the 3, yes 3, flimsy primary, secondary and whatever the heck the 3rd one is for, buttons, and forward and back buttons. Each one, apparently, has two modes, but again I never even got to try this. The company should spend a little more money on the switches for 2 of the 3 buttons and dump the 3rd and spend a little less on the packaging. Needless to say, after just an hour of trying to adapt to this trackball, it's already boxed, ready to go back Monday. Would I recommend this product? Well duh! Of course I would ... NOT!

I've been using trackballs for 30+ years; this appears to be a clone of the Logitech one (that go for $$$ second hand on ebay) - good for Elecom doing that. Easy to clean, reliable, just what you expect! Never sure about the elecom software, but you don't have to use it.

I bought this to replace my old Logitech wired tracker ball mouse as i couldn't find any other wired tracker ball mice on the market. the product itself is quite flimsy and is definitely not ergonomic, there is hardly and tilt to relieve the stress on the wrist. saying that it works fine and does the job of a normal mouse. if you are looking for a tracker to relive RSI then this is not the product for you. however if your looking for a mouse then its not bad at all

I've always used these type of mouse but this is the first time I have bought one that isn't Logic or Microsoft so I was a little nervous. The mouse was better than expected and I'm very happy with it. All the buttons work and do what they are ment to. It doesn't feel cheap or flimsy in any way. The only thing I will say is: it is very sensitive, the DPI switch on the top and the resolution sensitivity switch underneath does lower the sensitivity a little, but not by much. So the mouse can take a little getting used to. Altho I can see this mouse will be good for gaming because of how quick it is. The software you need to download (so you can access the third click button and a few nice features) is a little tricky to find and use, but again, once you get the hang of it, it's pretty good and worth having! Over all, as an experienced user of this type of mouse, I am very happy with this product. And the price is really good fit the quality of product too. I would fully recommend this product! I hope my review has helped you! ✌️
