Kensington SlimBlade Trackball Mouse (K72327U), USB

Recommend for people who know how to use this track ball

Took me a while to decide to opt for such a different style of mouse but it’s made a big difference not only to my personal comfort when working for long hours, but also to my work flow, and was surprisingly easy to get used to.

Although I returned it.. But it's very good if someone has no issue with size...

Great mouse, especially for my applications (sound engineer and producer). It's no wonder this is the industry standard mouse in so many studios.

After many positive reviews, I decided to try the SlimBlade, despite a few of the negative comments regarding the buttons. Please note, the comments on how mediocre this trackball is ARE the accurate reviews. While the device is nice enough, especially the ball itself, I don't think it's worth the high price being charged. The unit itself is rather lightweight and doesn't sit as solidly on the desk as one would expect from a premium piece of equipment. The mouse buttons are cheap plastic, weak, flimsy, tabs and switches that vary between, "did it actually press?" or "am I gonna break it if I press a little harder?" I really like the weight of the trackball, and the scrolling feature (rotating the ball itself) seems to be a love/hate thing...I'm one who loves it. There is so much about the mouse that I want to like and the trackball, scrolling and unit height are those things. That being said, the premium price you pay for the unit, versus the actually quality of the unit that you get are too divergent IMO. Considering replacing this unit for the expert, but that seems to have its issues as well. The quest for a good trackball continues...

Came on time, it was as they described it. However it’s not comfortable at all. Got pain in my wrist.

Fits the hand well. Easy to set up. I have been using a well known marble mouse for years, but it appears to be obsolete now. Any on the secondary market are horrendously overpriced, so finding this as a replacement is great.

I've been using Kensington mice ever since their early entrance into the market. They never failed me then and they are still #1. This track ball is "wireless". I had a wired Kensington mouse, but got fed up with the wire getting in my way at a very busy work station. It is battery driven and you will know when it's drained by the fact that the mouse pointer becomes lazy and won't go as fast as it should or you have trouble putting the pointer on any specific place on your screen. As far as I'm concerned, you'd be tragically missing out on possibly the best mouse ever made. And I stand behind it!

Desde que lo uso ya no se me cansa la muñeca, a pesar de que lo utilizo unas seis horas al día. He ganado en productividad porque, gracias a su gran bola, puedo situar el cursor exactamente donde quiero a gran velocidad. Los cuatro pulsadores de que dispone son grandes, sensibles y cómodos para usar. Aunque puede configurarse para que la pulsación conjunta de dos botones adyacentes sea equivalente a otro botón, esto no me resulta práctico porque es difícil hacer la pulsación simultánea.

6 años más tarde: He de decir, lo primero, que es igual de bonito y funciona igual de bien que el primer día. También es verdad que todos los días paso un paño para limpiarlo y hago lo propio con la bola. No obstante, creo que es porque lo uso mucho aunque no me atrevo a descartar el tiempo que llevo utilizándolo, a veces noto dolor en la muñeca por lo que he adquirido un reposa muñecas de gel que, aunque ójala fuera un poco más bajo, amortigua esa sensación. Por ello, si notas que apoyas mucho la muñeca en la mesa, te recomendaría que compraras también un reposa muñecas. Opinión de cuando lo compré: Es muy bonito (personalmente, lo preferiría negro y sin la solapa del lateral con la marca), tiene un tamaño perfecto y es muy liviano pero se mantiene firme en la mesa. Su utilización no puede ser más sencilla: en lugar de tener que mover la mano/muñeca y/o el brazo, se mueve una bola con un dedo, con varios, con la mano... Los botones inferiores, de grandes dimensiones, son los botones izquierdo y derecho equivalentes, de manera que el izquierdo puede ser activado con el pulgar, por ejemplo, mientras el resto de la mano utiliza la bola. Con el software de Kensington, en Windows y Mac, los dos botones superiores pueden ser utilizados para controles personalizados. Yo, que lo uso en Linux, he comprobado que el botón superior izquierdo hace la función del botón central (en los ratones de tres botones). Este dispositivo, ademas, incorpora la función de "scroll" (la de la rueda central de los ratones) cuando se usa la bola como si fuera un mando giratorio, que puede parecer extraño pero se acostumbra uno al instante. Definitivamente, es un dispositivo bonito, preciso y agradable de usar. Y aunque si bien es cierto que un dispositivo de este tipo no necesita moverse, por lo que el cable no es un incordio (como en los ratones), si fuera bluetooth, sería perfecto ;-)

I just got this trackball, first time using a trackball ever, i was delighted by how well this one works. the included wrist rest is really helpful especially for my hnda when on a hard surface, the ball rolls smoothly and with precision, the only slight thing is the scroll ring has a slight wobble to it, but it is not that bad, i am just very particular. but i do really like the scroll ring, i am able to operate the left click with my thumb and right click with my little finger. very easy to use and the optional kensingtonworks software is great, its not needed to use the trackball, but you can set so many options for the 2 programable buttons, the top 2 buttons are great, but you have to be very very precise about clicking both at once when using shortcuts, overall this was an amazing purchase, and i am impressed by the quality of kensington products
