Muito bom para quem procura um mouse para canhoto!!!

Overall, I think this is the best trackball available. I've been using trackballs for over 25 years and have used mulitple different brands of track over the years. The Elecom EX-G has the best feel and a great feature set and is far better than the Logitech competitor M570 (or M575).I have large hands, and I find the mouse feels comfortable in my hands. Even more comfortable than the more expensive Elecom EX-G Pro.The mouse offers a tilt-wheel, while most other trackball products do not. In addition to the expected left-click, middle-click and right-click, there is also an additional far-right button, two small side buttons that are assigned to page-up/page-down.I am a Linux user, and the EX-G is plug and play. The Mouse Assistant software is not available for Linux, and by default the far-right button is unassigned. But the input from clicking the far-right button is detected, so you can add a function to the far-right button in Linux if you want.While I think this is a great product there are a few minor flaws worth pointing out:1 - The scroll wheel encoder fails quickly. This will eventually lead to the the scroll wheel scrolling erratically, which can be very annoying. While I have repaired this by soldering in a replacement, it was somewhat diffiicult to do, and I have not found the exact part for replacement. The scroll wheel is the single-most reason I have had to replace these with a new one.2 - The right/left/middle click buttons seem about the same durability as the comparable Logitech models. If you use your computer a lot, that can mean you will wear out a button in about a year. But if you are capable of soldering, the mouse is relatively easy to take apart to replace a button.3 - The battery life is not the best. There is usually not much warning that you are low on battery, and the input will suddenly stop. So I recommend having a set of rechargable AA batteries for the mouse.4 - The Wi-Fi dongle is proprietary and appears to be dedicated to a particular mouse. While I have never lost or had the dongle fail on me, it could eventually be a failure point. It would be nice if the dongles could be re-assigned to another mouse.The flaws I have pointed our are mostly nitpicks. This is a great product and your best bet if you like trackballs.

First time I've worked with this type of static trackball mouse and it's great. Your hand stay still and you just move your thumb with the trackball, which I find makes it more accurate than the typical mouse where you move your whole hand.I thought there was going to be a learning curve of a few days but no, it's a pretty quick, same-day adaptation. I find that the wheel and back and forward buttons are easier to use and more functional than the Apple mouse. You don't get mixed up, they are clearly and intuitively separated and it flows.I've had it for a month, I didn't download the software that I understand could add some functionality but I may do so later.The unsual thing is that I'm using it with the USB adaptor in my M2 Mac Mini but it's not bluetooth nor wireless, so it must be another radio frequency that doesn't show up on the computer. Cool, in a way, so it doesn't load bluetooth or wireless channels.I really like it, a definite must-try for lefties.

es cómodisimo, y muy conveniente no tener que estar deslizando por todo el escritorio el mouse!!

I've been using Trackball mouses for more than 20 years, but on these last months I can't endure long sessions of PC usage or gaming anymore. Mi right hand and wrist end up stiff and hurting. That's why, even though I'm right handed, I decided to learn to use a Left handed trackball, so that I can alternate between both hands.I didn't look too much into the perks and features of this model. It just seemed nice and affordable (even with the addition of shipping costs to Spain). But boy was I in for some pleasant surprises.I was still using the old version of the Logitech M570 (standard left and right buttons, wheel + wheel button configuration plus 2 additional customizable buttons). Now, I don't know about the recent M570 v2, but this ELECOM, compared to the old M570 wins by a landslide, let me tell you...First of all, when you rest your hand on the mouse you get a feeling as if the shape of the hand was kind of sculpted into the mouse, as if you had slightly pressed your fingers on some clay and then it had dried.In addition to the usual left and right buttons (which you normally would press with your index and middle finger), there's one extra for your ring finger.It has also two additional buttons for the index finger (similar to those of my Logitech), and -the quirkiest- the wheel not only works as an up and down scroll and button, but has also a right and left tilting movement which function as TWO MORE buttons. The neat part is you can assign any key or keyboard functions (and even most combinations of keys except Ctrl+Alt+Del for safety reasons, or so it says) to each of the buttons.The configuration software is NOT provided on the eco-friendly sober packaging (nice touch). You just get the mouse, the small USB receiver (which you can attach to the back of the mouse for storage or transportation), the needed battery (another nice touch) and a brief quick start guide in japanese, but with enough annotations in English to succesfully start using the thing.Speakinf of the customizable buttons, I find REALLY useful to have CTRL+C and CTRL+V (Copy and Paste) on the left and right wheel tilt buttons. Also the SPACEBAR and ESC on the index extra buttons and right now I have "maximize window" on my ring finger one, which suits my current needs for one of my most used programs.By the range of functions assignable to the buttons, it's clear that this mouse is meant to be versatile not only as a gaming mouse but mostly as an office worker mouse. It must be great for Excel users, and maybe photo or video editors too. Also for enviroments using more than one screen.It has another function called "flying scrolling", in which you can use your mouse wheel not for manually scrolling but to start and stop scrolling. Not useful for me at the moment, but I understand it can save a lot of manual flicking in many scenarios.Since I'm not a hardcore gamer (mostly point and click adventures and puzzl-like games) I cannot say for sure how this mouse behaves as a gaming device, but I reckon that must be good. It has a DPI selector, which is also new for me, so that you can choose between covering about 60% of the screen (horizontally) with one movement of the thumb rolling the ball, or covering the whole screen in less than the full range of the ball. I'm sure that must be handy when trying to shoot zombies or whatever kids are doing nowadaysOn the bad side (but not really): Call me old schooler, but I miss the days of having a phisical copy of the drivers and software included with the periferials. That's the only "con", if any, that I've found on this mouse so far. But all in all I find it a great product, I am very satisfied with the purchase and I think I'll end up buying the right handed version also. I'm finding that controlling this mouse with my left hand is a lot easier than I anticipated. But I wonder if I'll be able to edit video with 2 mouses at once with SO MANY ASSIGNED BUTTONS (lol). Maybe I'm on to something here, who knows...You don't have any way to confirm this, but I assure you that ELECOM has not paid me anything for this review, I kid you know. I REPEAT: ELECOM didn't sponsor this review, nor did they promise me to send me the right handed one... yet. (But surely wouldn't hurt, either, wink, wink).
