It fits into the rest perfectly and stays in place, so long as you don't pick it up. The ball itself is a large, smooth sphere of shiny red plastic.
The panels are loud and frankly a bit springier than what you find in most mice it's mostly a non-issue, but can occasionally become a distraction.Īround the ball is a textured scroll ring that looks a bit like the ring around an old kitchen timer. The roughly rectangular block, measuring 2.7 by 5.1 by 5.8 inches (HWD, including the ball), has four large, triangular click panels that frame the hemisphere crater in which the ball sits. The Perfect Trackball? Roll With Me Hereįor an "expert" device, the Kensington Expert Wireless looks and feels quite simple. A few improvements could be made and power-user features added, but the Expert Mouse earns an Editors' Choice for providing everything you need to adapt to the trackball lifestyle. Plus, it’s cordless, so less desk clutter. The $99.99 Expert Mouse Wireless Trackball is comfortable to navigate, and compact enough to suppress strenuous motions. It should come as no surprise that Kensington, a company known for making trackballs, would design what I see as the platonic ideal of the form. They offer economy of movement-all the work falls to a few fingers that, while they move a lot, never have to stretch. But if you have wrist or shoulder troubles, trackballs keep your whole arm still.
It can feel strange to switch from using a mouse, which feels like an extension of your arm, to rolling a ball to move your cursor. Like many ergonomic products, trackballs are an acquired taste-often, acquired by sheer painful necessity.
