Elecom EX-G Trackball Mouse, 2.4GHz USB Wireless, Ergonomic Design, Thumb Control, Smooth Precise Tracking Roller Ball, 6 Programmable Buttons, Tilt Scroll, Computer Mice for Laptop PC, Windows & Mac

Good trackball fits my hand very well and is very comfortable to use. accurate and all the controls work well. The third finger switch for temporary slower movement of the pointer I never used but I do like the forward and backward switches beside the left hand finger switch. No battery issues , it has a nice docking station on the bottom of the trackball for the dongle. The ball fits in its holder very neatly with very little side to side movement and has a smooth easy movement when in use. the low and high dpi selection on the on switch seems to do very little but that maybe just me as I found it very good with little need to vary the settings. This trackball is very good and I've now bought second one for my wife who is impressed to. Good value for money.

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! ✌️

Got this as I have some issues with my wrist and I'm a office worker. I find it has changed alot for me. Not as much pain. It takes a few hours to get used to the rollerball but worthwhile. I don't think I'd go back to a normal mouse. It did stick a little at first, but doesn't now as I've wore it in a bit. I've not used this for gaming, I've used this to help me reduce pain and it has.

I cannot go back to a normal mouse. It is so easy and comfortable to use! I just love it!

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!

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.
