    Customers like the comfort of the mouse. They say it has a nice feel, has no stress on their wrist, and the main buttons feel ok. The mouse allows them to relax while searching the web and is perfect if they have small hands.

    Customers are mixed about the quality of the mouse. Some mention it's top notch, solidly built, and a really nice device. However, others say that the overall quality isn't the greatest, the accuracy, ease of use, and features are very iffy, and the whole thing felt cheap and flimsy right out of the box.

    "...But other than that, its terrific. Fast, accurate, comfortable. And at fair prices... i highly recommend...." Read more

    "...This mouse has held up amazingly to all the road-wear I've thrown at it with travel/working in 2 locations and switching between PC and Mac...." Read more

    "...on using, or some combination of the two, but Elecom does not make good trackballs. They certainly shouldn't be demanding the $40-$70 they do...." Read more

    "This may be one of the best high tech mouse out there but for me it has too many buttons. Too confusing for an older person." Read more

    84 customers mention46 positive38 negative

    Customers are mixed about the button of the mouse. Some mention that it has numerous programmable buttons and the buttons are laid out in a similar fashion to the trackball. That said, some complain about the odd right click button, the middle clicking being a little tough, and the back and forward buttons not working for any browser.

    "...The buttons are all nice and responsive. Middle clicking is a little tough for my taste, but most mice are like that these days...." Read more

    "...bells and whistles.. The only real issue with it is customizing the extra buttons. The software they provide is garbage...." Read more

    "...There are extra buttons, which is great. I'm assuming there's software to program them...." Read more

    82 customers mention47 positive35 negative

    Customers are mixed about the performance of the mouse. Some mention that it works great and does everything they would expect, while others say that it's ineffective and not useable. The mouse functions perfectly, and all the button clicks with crispness. However, some customers report issues with the trackball, saying that it simply refused to respond and does not function like the conventional scroll wheel.

    "...Company's software for Mac - El Capitan works great for programming buttons. NO COMPLAINTS!------------..." Read more

    "...massive monkey paw encompassing the entire device, this thing is NOT at all useful for any heavy graphics work!..." Read more

    "...Hard to tell if you are selecting or tilting until it is too late. It works fine, but sometimes when pressing down and holding you go from normal..." Read more

    "...it worked great initially as the first one had but completely stopped working after only 8 weeks...." Read more

    70 customers mention28 positive42 negative

    Customers are mixed about the smoothness of the mouse. Some mention that it has very smooth scrolling of both the thumb scroll wheel and the trackball. They say the track ball moves smoothly and is easy to pop off to clean. However, other customers say that it doesn't work for any browser, the scroll ball is a little rough to roll, and the cursor doesn''t move at all. They also mention that the scroll wheel requires too much force to tilt.

    "...Side scroll wheel needs improvement. Hard to tell if you are selecting or tilting until it is too late...." Read more

    "...The scroll wheel is absolutely awesome, just great movement and textured so you never slip. The back and forward buttons work well...." Read more

    "..."grab" the ball and make it stick in place, making small and precise mouse movements difficult...." Read more

    "...really smooth and I haven't had any tracking issues, ie: no hiccups in movement etc. Only time will tell how the optics stand up over the longer run...." Read more

    61 customers mention25 positive36 negative

    Customers are mixed about the ease of use of the mouse. Some mention that it's easy to use with just several buttons, and easy to program keys. However, others say that the instructions are all in Japanese and the mouse has a bit of a learning curve.

    "...The instructions are in Chinese I think...." Read more

    "...The left click is perfectly positioned, right click is easy to get used to...." Read more

    "...The ball was big enough for basic computing but gaming was a little difficult due to the ball being smaller than many competitors...." Read more

    "...I mostly use it for day trading, It's easy to use but takes some time and practice to get used to the functions...." Read more

    57 customers mention21 positive36 negative

    Customers are mixed about the size of the mouse. Some mention that it's appropriately sized for their smaller hands, while others say that it is a bit too small.

    "...Just odd placement/shape. The ball also feels small, but I believe that should the mouse last long enough, I should be able to get used to it...." Read more

    "All in all a great product. Size, feel, quality all on par or better when you consider price...." Read more

    "...Cons:I have large hands for a woman and it is a little bit too small,It uses up batteries fast, especially in the high DPI mode,..." Read more

    "The roller ball is kinda smaller than the ones I have on other PC’s. That’s the reason for 4 stars. Other than that, it’s perfect!..." Read more

    30 customers mention14 positive16 negative

    Customers are mixed about the accuracy of the mouse. Some mention that it has accurate tracking, good button layout, and powerful customization software. They say that the response on the trackball is very precise and has very sturdy feel. However, others say that it lacks precision and sometimes has jumpy movement. They also mention that the mouse is not as precise as a mouse and that the rollerball skips.

    "...3. Mine broke after about four months. The dongle no longer finds the trackball...." Read more

    "...But other than that, its terrific. Fast, accurate, comfortable. And at fair prices... i highly recommend...." Read more

    "...ever had is about 1/3 of the trackballs I have bought have TERRIBLE tracking problems...." Read more

    "...The ball moves effortlessly and is as precise as an=y other I've used. The left click is perfectly positioned, right click is easy to get used to...." Read more

    Great but...Base grips are worthless!
    3 Stars
    Great but...Base grips are worthless!
    Love this travel-sized trackball as it's appropriately sized for my smaller hands. I'm an avid gamer and have always used trackballs due to my hEDS to minimize fatigue and help prevent repetitive-use injuries. The accuracy is decent enough for gaming once you make a few modifications to it using the dL-able software. The scroll wheel is a nice addition as well as the extra buttons that can be programmed to suit your needs.My main gripe is that I bought this smaller trackball version in Sept 2021 as a secondary trackball, and the rubber grips are already destroyed as of Feb 2022. No replacements are available, just like my previous DeftPro trackball (which had the same issues and actually prompted this purchase to begin with.) I miss my Logitech and Microsoft trackballs, both were serious workhorses that never gave me issues with the grips below and each of those lasted ages! 😔 I guess I'll have to figure out a new method for creating my own replacement grips for both because the sticky residue they leave behind is annoying and difficult to clean off surfaces and there really hasn't been any progress in convincing Logitech or Microsoft to be kind (or caring) enough about the disability community by re-releasing their trackball lines again.

    5.0 out of 5 stars Buena relación calidad-precii
    Reviewed in Mexico on February 3, 2023
    Este es el segundo que compro y llegué a él después de tratar el Logitech M520, M570 y un mouse vertical. Este modelo me resultó el más cómodo ya que un mouse convencional me ocasiona muchas molestias en mi extremidad, cuello y espalda. Me gustan los botones programables para cada aplicación, es decir, puedes programar, que el mismo boton haga algo distinto dependiendo de la aplicación que estes usando y combinando hasta tres teclas simultaneas en cada boton. Las "desventajas" son la duración de la pila (unos 3 meses), no es muy preciso y el software puede ocasionalmente no reconocer la aplicación que usas haciendo que los botones programable no respondan como deben. En general, si tienes problemas de mobilidad y no requieres mucha precision, es una excelente opción.
