ProtoArc Vertical Wireless Trackball Mouse, EM05 NL Bluetooth Ergonomic Rollerball Mouse Rechargeable Computer Laptop Thumb Mouse, 3 Device Connection

Must buy for 2026 setup. It’s been still about a couple months and still can’t fathom how perfect for my need. I don’t have to move my hand around only the thumb and barely any strain after full day of work. Very underrated product.

Best mouse I've had so far, used to own a Logitech ergo m575 which was good for short bursts of usage but for longer workdays I felt pain in my palm and the joints of my fingers, did a bit of research and decided to try a mouse with a more neutral handshake position and it's the best decision I've ever made, pain is gone! Also high quality build, smooth scrolling, great feel, all around quality product

Nice

Used Apple mouse and started having pain in hand so got this.Learning curve is not that steep and comfortable.

Track ball is good quality and very comfortable to use so far but at 4k INR price the plastic quality is cheap so not sure how long will it last. But in the price range, probably the best one in Amazon.in for large hands

I liked it. My wrist is more relaxed.Im using it with combination of split keyboard and my experience has been awesome 👌.

Avant l'achat, je n'étais pas convaincu mais je me suis dit pour le prix, je vais l'essayer. Lors de la réception de la souris, l'emballage est digne d'une grande marque voir plus. Mais quand j'ai vu la souris et j'ai essayé, testé.... Wow ! Sérieusement, la qualité de fabrication, la solidité, le confort (++++), c'est beaucoup mieux qu'une souris d'une grande marque que j'ai eu à meilleur prix.J'ai une grande main et je n'ai pas besoin de replier ma main pour atteindre un bouton, ils sont à la portée de mes doigts. Bref, bien content, pour moi, c'est 5 étoiles.Un seul hic mais rien de majeur, la roulette de défilement, je l'aurais placé plus haut (sur le top) plutôt qu'entre les deux boutons droits et gauche. Mais plutôt de défiler avec l'index, je le fais avec le majeur, question d'habitude à prendre je pense.

This is an initial review after a full day's use of the mouse, but I'm pleased with the mouse so far. I didn't think I'd find an upgrade to a rollerball mouse, but even the small things, like the buttons on this mouse, and the placement, already make my functional use so much better.I really liked my previous mouse, actually my last 2, but in each new upgrade, the angle of the mouse and reach of the ball felt a little more comfortable than the last. This is an exceptional upgrade in how my hand feels holding the mouse, moving my thumb, and using the buttons. It took a minute to get used to the new position, then realizing the functions of the buttons, quick ease to change the cursor speed, not that I need that much, but useful. The forward and back buttons, especially useful in webpage surfing, is great, and easy to get to without really thinking about the button placement.The real think is the comfort of mouse setting. As I deal with maps, imagery, and coding, I don't like taking my eyes off the screen, and should be able to find my keyboard and mouse easy just by last placement, not by eyeing where they are. This should be a comfort level. As I'm already used to a rollerball mouse, this placement is already good, but now putting my hand down on the mouse, the way this mouse sits just feels more comfortable, and the wear and stress on my thumb is lower. This, however, is on personal use of the mouse. I've used flat rollerballs that use index finder, index and middle, and thumb rollers. I can function with any with ease, but extended use tires the fingers, especially from mouse to keyboard, moving screen items and typing. So far, I like this mouse.The design of the mouse seems to take up some more space than my previous model, I think mainly how the bottom of this spreads out for stability and comfort on your palm. Using this in conjunction with a small gel wrist rest, feels really comfortable in prolonged use.I have been really friendly with Logitech products, especially like their rollerball mice, and it comes down to the tracking. The last mouse was an off brand. While the mouse was nice, it held up well, the tracking and smooth movement wasn't there. For general document management and webpage surfing, it was fine. For precision work, it was not. The tracking on this, so far, is perfect, smooth, but this is so far just the first day use. Let's see over time. My previous off brand, tracking was never smooth, and sometimes quite frustrating. I'm not seeing with this, so far.I like this mouse, it's held up well to the first day use. It charged up well, came with minimal charge to at least get started, then we useable while charging. I'm using the USB, but this has Bluetooth function, if you go this direction. I'm happy with the USB. I'll write more later on the other connectivities.Each mouse is dependant on the user, use, function, and wear and tear on the hand placement, finger use, and overall ergonomic comfort. This works very well for me, thumb use, and placement of the hand. If you get a lot of thumb wear, this has some ease to it, and when not using the thumb, it has a natural resting place on the mouse. And the button functions, in turn, make this mouse quite functionable.

Para uso diario y prolongado es la mejor opción, no cansa la mano y te permite mantener una postura relajada. Y con su configuración puedes variar la velocidad de respuesta, lo que lo hace más cómodo al adaptarlo a distintas actividades.

Un muy buen producto, se siente de buena calidad y es súper útilAl principio es un poco raro para adaptarse a él, pero después de unos minutos de uso es súper intuitivoLo recomiendo 10/10

Wasn’t sure I would like the vertical trackball but I’ve grown so used to it that it’s now my preference. The battery life is great and the buttons are holding up well. Much easier than a mouse for RTS games in my opinion. The cursor can jump quickly by default but you can adjust it in the settings. I like this one and will probably get it again when it breaks down. Seems pretty sturdy though so I’m expecting at least a 6-7 year lifespan here.I’m 6’2” with average hands for my size. The feel is nice and the wheel works great. It’s a little bulky so many not your “travel” trackball but a perfect one for the default desk work.
