Review on Kensington Orbit Trackball Scroll K72337US by Jason Flippen

I have used most of the large trackballs that Kensington has specialized in over the years. Expert mouse, Original Orbit, not Slimball (maybe someday), now Orbit with scroll ring. They are one of a kind - it's rare that someone makes a similar trackball. Thenar eminences are not always the same, which is why Kensington enjoys some popularity with the public. The most important thing to know about these balls is their size. The Expert mouse is the largest and you can probably concussion someone if you throw this ball hard. The Slimblade is slightly smaller and the Orbit is the smallest that still feels like a fingerball. Size is the attraction, and that means you have something between a 'grip' like a mouse and a 'travel' like a touchpad, with a tactile feel that's great for swiping the screen as well as fine-tuning suitable. Precision of movements - if some fingers get tired, they can turn off, group or even stroke the ball. Does this mean that the Expert Mouse is the biggest and best? Some. When mobility is your priority, the Expert Mouse's size and weight become an issue. In addition, the bullet is not fixed by anything, so if you try to move the case, it can fall out with a bang. And return the ball to its place? Another knock too. Not suitable for electronics. You want it installed and repaired in one place. The Slimblade almost looks like an Expert wearable mouse, but that flat body is a disadvantage in terms of ergonomics. Older Kensington designs are low voltage when positioned correctly: you can squeeze your wrist and relax everything when you're not moving. Slimblade encourages sagging or overpronating, which is not a good idea for a long time. Orbit now. The original Orbit was a very simple two-button deal. It didn't have a rolling ring and the ball fell out too, but it was smaller and that had many advantages. None of Kensington's designs lend themselves to button access in daring gaming scenarios, and gaming isn't their forte, although you can certainly play an FPS game and still feel competent at a non-competitive level. If you immediately double back, you'll have to fight the ball a bit to do so. The Orbit is actually best suited for gaming due to its smaller size, and its ergonomics are still pretty good. Because of this, it has a versatility that makes it more convenient for general use. But the lack of scrolling wasn't a big problem! This new Orbit has a scroll ring and grips the ball on the edge enough to hold it in place when you turn the case upside down, having previously fixed all of the biggest bugs. There are still only two buttons instead of four on larger models, but in general that's normal. Using it saves a ton of desktop space, and if you really need more assignable keys, I'd suggest macro keyboards. Productivity users know what they really need. Defects? The palm rest is as slack as ever. It works well, but it doesn't snap into place cleanly.
