Kensington Expert Mouse - Wired Ergonomic TrackBall Mouse for PC, Mac and Windows with Scroll Ring, Ambidextrous Design and Optical Tracking - Grey (64325)

Product Information

How can I change it back to scrolling slower or line by line, or whatever setting it had that didn’t go 1/2 page at a time?

Designed for PCs and Macs, the Expert Optical Trackball employs Kensington's DiamondEye optical technology for smooth, precise cursor movement. These issues are endemic to all trackballs, not just the Expert Mouse Wireless, so I'm not criticizing Kensington here. The trackball mouse comes with TrackballWorks ™ software which allows you to customise the mouse to meet your needs. Adjusting the cursor sensitivity so the cursor moves the amount you feel it should as you roll the ball is essential to the experience. I would find it very hard to give up the comfort and accuracy of the Expert for another finger-operated trackball.The ambidextrous design is exactly symmetrical so the Expert can be used by right-handed and left-handed people.

It appears that Kensington in their wisdom wanted to have it moving in small steps so they introduced a magnet. Ergonomic mice can help with conditions like Carpal Tunnel Syndrome, Repetitive Strain Injury and Arthritis. Ergonomic mice are quite diverse and one that is correctly specified will not only meet your physical needs, but also help you to optimise your workspace. The new version, KensingtonWorks, is a simple, utilitarian program that lets you make crucial adjustments to the trackball's sensitivity and button-mapping. I love the design and functionality of the 3Dconnexion SpaceMouse Pro Wireless, but it’s not for 2D.Just like any other trackball or mouse, the buttons will show signs of use after a few years of intense use.
