Kensington Orbit Trackball Mouse With Scroll Ring (K72337Us)

Perfect as all Kensington products. Will buy one more

Great to use for both hands. Very useful wheel to scroll The removable Little wrist extension ramp means there is no need to use extra padding and supports the wrist

Muito bom mesmo. Sou canhoto, e estou acustomado com O Marble Mouse, que usei uns 10 anos. Esse é mais largo, e um pouco mais dificil coordenar os dedos com botao/bola para selecionar texto. A bola roda super bem e a roda de scroll é otima. Funciona no Windows 11 sem fazer nada. 2 ressalvas: 1) Tamanho maior que Marble Mouse e deslizamento perfeito, sem fricão da bola, dificulta um pouco a precisão, cordenando dedo anel e indicador (sou canhoto). Mas nada que não da p/ aprender com tempo. 2) Essa parte para apoiar a mão... É muito confortavel com, 10x melhor que sem. Pulso fica reto. Mas... a fixação é meia boca. Imaginei algo mais... firme. Não sei porque não fabricaram o mouse junto com a peça. Funciona, e depois de colocar não vou usar sem, mas estou imaginando que, no futuro, vou ter que colar ela para uma fixação mais permanente. Mesmo com as ressalvas, 5 estrelas, É muito bom.

If you're needing more than two buttons, this is not the mouse for you. There's another few versions with more than two buttons. I love it. The ball is big enough, the ring is fun to play with, and it's good if you use two fingers. I use mine for work and get comments (not many people see trackball mice any more), and it's good for that (no cad, mainly admin and typing and reading.) The bearings do get a bit dirty, so give them a clean once a week, and they feel much nicer after it's been worn in a while. The software is meh, but that's only because this one has two buttons. They click nicely. They could be a bit loud if you're requiring deep silence or doing a load of clicking.

I picked up this trackball for work many, many years ago, and I have to say that i'm pretty impressed. It doesn't have a lot of bells and whistles on it, and the build quality could be a little sturdier, but what it does it does well. It's only got two buttons and the wide horizontal scroll wheel, but that's really all you need with a trackball, unless you're planning on complex gaming or advanced design work. It's pretty comfortable, and the additional rubber wrist pad they provide actually does help the overall comfort level of trackball in my opinion. But lets talk about the horizontal scroll wheel. It's distinctly strange as far as scroll wheels go, and although I'm sure there are those that won't like it, or find that it's not comfortable for them I am not among them. I love the scroll so much so that it actually got me to start using the scroll function at all. I previously thought the scroll function on computers was nonsense in general, but after using this scroll wheel I realized that I just hate most scroll wheels. It's connected rather loosely to the trackball housing which really lets you spin it if you want to, or give it a soft touch just as easily. The placement of the wheel is extremely intuitive to me and I find using it extremely natural. Although the general build quality is only OK, I've broken the left click on one of these trackballs from overuse while gaming, I have to say that the truly incredible scroll wheel and low price of this mouse make it for a really great overall product. I've bought three of them over the course of the last eight years, one for the office and two for home, so I can definitely say that I'm a big fan, and I'd love to see the horizontal scroll wheel of theirs on some higher end or more premium trackball units!
