Sin lugar a dudas es un excelente producto, tenía rato queriendo uno y me fascina!Lo recomiendo, llego a buen tiempo y bien protegido

Muy util

Yo cambié de un mouse vertical por este trackball, llevo 2 semanas usandolo y ya empiezo a tener dolor en la parte superior de la mano, realmente me he sentido más cómodo con el mouse vertical.Por la parte de los materiales y funcionalidad es un gran producto, funciona bien y se ve muy padre. Quizá el vendedor debería agregar algunas fotos o instrucciones sobre como usar el producto para que sea realmente ergonómico.Es una lástima, realmente me gusta el producto pero tendré que regresar al mouse vertical.

Avevo già avuto esperienze in passato con le trackball e ultimamente si è ripresentata l'esigenza. Ho trovato questo prodotto di Kensington e dopo averlo acquistato posso dire che sia stata un'ottima scelta. Il prodotto è solido e ben costruito, si collega al pc attraverso la sua chiavetta wireless inclusa oppure in bluetooth. L'ergonomia e la manovrabilità sono ottime, anche la precisione del controllo è all'altezza delle aspettative.Unico piccolo punto negativo è il design dei tasti che termina a spigolo vivo e a volte, scorrendoci sopra con le dita si tende leggermente a toccarle.

It works quite well, but If I compare quality or at least the feel of quality it is not the feel belonging to 100 euro's. I had a logitech before (but problems with my thumb) and if you take that as standard, this kensington has the feel of one of 30 euro's.But maybe the quality is there and it will prove that to me by functioning perfect for the coming 5 years and I can come back for more stars.The software works, but isn't very nicely done. Again, it works so when you have set it, you don't have to do till you take a new computer. Tip for the manufacturer. Don't present a drawing where the dongle had a place in te mouse and then hide it in the cartons :)So for sofar a 4/5 for function and a 2 for the way it looks for that amount of money, making it a 3 stars item. Hope to come back to add stars as the quality is better then it looks at first sight.

Me tomo un tiempo acostumbrarme, pero es mucho mas comodo que un mouse, definitivamente recomndable si trabajas mucho en pc, siento menos molestias, algo que siento incomo es el click derecho por default, pero lo puedes reprogramar y ponerlo en uno de sus cuatro botones, como se dese, en conclusión es un mouse excelente

Es el cuarto trackball que compro de kensington y como siempre, funciona de maravilla. A pesar de ser de tamaño grande, una vez que te acostumbras, es muy útil para trabajar largas jornadas. Para sacarle la mayor ventaja, recomiendo programar los cuatro botones y sus combinaciones, así como la rapidez de movimiento, pues en mi caso, utilizo 5 pantallas y requiero un movimiento más rápido.

Initially had some software problems which is fixed with updates, now it works without any issues. I tried all sorts of trackballs and found the larger the 'ball' the better, and this is certainly the biggest in the market I can find. I tried thumb trackballs, but they 1. sores out my thumb joint fast and 2. impossible to clean as the balls are 'locked' in the socket (at least when I was using the Logi Trackball mouse). I prefer the trackball because I move it with my middle three fingers instead of the thumb, the movement is shared, and also requires far less movement on my fingers than if I use the thumb alone. The tracking works wonderfully well (after the software update), and I can scroll up and down pages easily with my ring finger. All in all, after 20 years of trackball use (used Logitech Trackman the most prior to this), this is definitely the best in terms of accuracy, ergonomy, functionality that I've come across. Highly recommended.

Se conectó de forma fácil y rápida a mi computadora por bluetooth, no tuve necesidad de usar el usb que incluye, es totalmente funcional y preciso, cómodo, de muy buen tamaño (grande) y no extraño mi antiguo mouse ergonómico y mas caro que este, incluye baterías, se apaga cuando no se usa por tiempo prolongado, se prende al dar click y se conecta de inmediato.Yo ya estaba muy contento cuando voy y bajo la aplicación en la pagina oficial, compatible con mi sistema operativo High Sierra (es antiguo) y configuré todos y cada uno de los botones.Ahora tengo un trackball totalmente personalizado incluso para cada aplicación pro que uso, encima se ve genial!

Primero debo empezar diciendo que soy un gran aficionado a los periféricos.Mi afición nació de una necesidad muy puntual. Ser mas eficiente en lo que hago. Verán, durante mucho tiempo lo único que usaba era una mac, y el trackpad me parecía (y sigue pareciendo) de lo mejor que existe.Mis primeras compras iniciaron cuando por cuando por cuestiones laborales tuve que empezar a usar ademas de una mac, una windows. Al principio tenia dos mouses, teclados, etc... con el tiempo introduje a mi setup toda la linea flow de logitech un MX 2 y un K780 para la oficina, y un Anywhere 2s y K380 para cuando tenia que viajar (viajaba mucho).La situación cambio completamente cuando pego el virus, y en lugar de pasar 50-50 oficina viajando, pase a estar 100% home office. Mis problemas empezaron cuando empece a utilizar un teclado mecanico completo, y no me quedaba lado en el escritorio para el mouse (es un escritorio para zurdos, con el archivero de lado izquierdo).Este mouse esta de la misma altura que mi teclado mecanico, por lo que puedo tener el mismo angulo, y lo puedo tener del lado izquierdo de mi escritorio y rapidamente pasar la mano izquierda del teclado al mouse. Cosa que al ser zurdo se me hace completamente natural y muy fluido.Mi unico problema con el seria el precio. Probablemente a precio regular no lo compraria, pero al precio que lo consegui que es el mismo que la version con cable, me parece una super compra, y vale completamente la pena

A trackball is nothing I would have considered in the past as most of my PC time is used for gaming and being able to do work has always just been a "bonus" of the platform. However, over the course of the wonderful year of 2020, I had to find solutions to working from home and purchased not just one, but two trackballs. I first started with Logitech's M570 (wireless) and followed it up a couple of months later with the Kensington Expert Wireless. Chances are that if you're seriously considering transitioning to a trackball, you are looking at exactly these two models or their wired siblings.Both solved a very simple problem of making the most of confined space. For my gaming and personal PC, I have a typical desk setup with a brick of a gaming mouse, but for the work laptop I lugged home with me, the idea was that it was a temporary thing and I'd be back in the office with a full desk in no time. Three quarters of a year later and the work machine is growing roots in an old TV table. I managed for a very long time as I was quite comfortable with simply using the built-in trackpad, but when they replaced my machine with a new one, I could no longer work without wanting to throw it out the window. The 'brilliant' minds that designed the new trackpad clearly never used one as they removed the physical buttons that bisected the pad and made the pad itself one giant button that would only right click if you used the very bottom right corner. So now I needed a mouse, but TV trays don't have the runway for effective mouse use. Enter the trackball. Since trackballs stay put, they can sit comfortably in a small space and you still have full use of your cursor.The second thing both trackballs solved was the right-click issue. While the M570 has more traditional placement of buttons like a regular mouse, the Kensington Expert (herein "Expert") has four fairly large buttons that can be tapped easily regardless of what hand position you take. Since the laptop's trackpad cut the right-click distance by 2/3rds and I live and die by context menus, I needed that functionality without feeling the need to break equipment.The above issues are solved by pretty much any trackball device available in the market today, so what it really comes down to aside from general reliability and longevity is preference. First off, while the M570 seems sturdy enough, the Expert feels like a tank. It has a fairly large footprint compared to the relatively mouse-sized M570, but the Expert also has a much larger ball (maybe three times bigger?) and is heavier and kept in place with rubber feet. As mentioned above, it has four large programmable buttons surrounding the trackball and a rubbery ridged wheel that provides you with your scrolling (compared to Kensington's Slimblade which has you twisting the ball in the socket to scroll instead). The Expert uses the bottom left button (by default) for left click and the bottom right for right click. Since the ball is finger operated as opposed to thumb-operated M570, you typically use your thumb and pinky to click and right-click respectively. It takes some getting used to, but it really becomes second nature pretty quickly. On top of that, you get two extra programmable button assignments by clicking the top two or the bottom two buttons together.Despite its wider footprint, the Expert has become my go-to device for work while the M570 has been repurposed for the media machine I have connected to my TV. While it comes with a very sturdy wrist pad to help with your ergonomics, since I sit higher than the Expert instead of level with it, I find it feels better without the pad attached. The larger ball is much easier to manipulate and makes more logistical sense than when using the thumb ball of the M570 and Kensington's software allows you to set up keyboard hotkeys to assist with accuracy. For example, I can hold the Ctrl key to drastically slow down the cursor (this is completely customizable) so I can select specific things or position the cursor with precision.For cleaning, the ball is held in the device by gravity only and can be easily lifted out without having to lift the base unit (and it's kinda fun to do that anyway). Underneath you'll have access to the sensor as well as the three beads or skates that the ball rides on. I don't find that the ball is a dust magnet, but normal use will see crud accumulate either on it or on the skates. It's easy to simply lift the ball and give everything a wipe down.There's only two things that I am nitpicky about when it comes to the Expert. First, the ball has a very high profile (exactly half of it is exposed) and while I find it very comfortable to use throughout the day and experience no wrist strain whatsoever, it would have been nice if the 'horizon' or the plane of the base unit was a bit higher and the ball sunk a bit lower (things addressed in the Slimblade). The second thing is that this thing puts itself to sleep, which is admittedly a good thing. However, you cannot wake it by rolling the ball or scrolling the wheel; you must click one of the buttons to wake the device from sleep, but the click is actually registered with the OS and is not thrown away. Therefore, unless you're expressly positioning your cursor safely when you go idle, then you need to be careful on what button you press to wake your device. Neither are dealbreakers, but I really find the registration of the wake input to be weird.Overall, I am very happy with both of my purchases, but the Expert won out as my day-to-day solution for work. I would never use the device for gaming (at least competitively), but its customizable configuration from speed to keystrokes with Kensington's lightweight software easily make it a power-user's device. It may be unintuitive at first, and I was always first in line to mock these devices, but I have completely turned around on them. I think wherever I go in my professional life, the Expert will come with me.

Excelente producto, muy buena funcionalidad excepto por el software, no sirve y la página que mandan a descargar no funciona! Fuera de eso, es excelente producto!

Expensive but good
