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

Product Information

I purchased it about 4 years ago to replace my Microsoft trackball (this was flat out the best mouse ever, sadly no longer made, and cost on the hundreds used). Automatic shutdown:Yes

Then you’ll be pleased to know that we offer flexible payment options including PayPal Credit and Klarna Pay in 3.

I’d prefer a red ball, the grey one makes the whole thing look a bit industrial and unfriendly, but then I like red balls too.

It's easy to roll the trackball accurately over short distances and to make fine adjustments, but long rolls—like what you'd use to travel across a dual-monitor setup, for example—are generally imprecise and require corrective motions that require more deliberate thought than a standard mouse. Optical tracking with the mouse is highly accurate with DiamondEye ™ movement detection technology providing smooth, precise cursor control. If the trackball feels “sticky” (does not move around freely) I clean it and wipe it with a small amount of uMicroLubrol Ultimox 226 and then all is well again.This also depends on the position of your arm, chair and desk, so it’s nice to have the option of adding or removing this wristrest depending on your situation.

The free downloadable software provides an even more personalised experience, giving you the ability to assign a wide variety of program functions to each of the 4 buttons, as well as controlling the pointer speed and scrolling speed. The four large buttons can be programmed to do exactly you want, all making for a simple and effective workflow with minimal movement from your hand and arm. These clean high quality materials are then sent directly to our recycling partner so they can be put back into the raw material streams. Explore Comet and discover a constellation of products from washing machines and fridge freezers to air fryers, 4K TVs, laptops, consoles and more - it’s easy to find everything you need for your home in the Comet universe. Ergonomic mice can help with conditions like Carpal Tunnel Syndrome, Repetitive Strain Injury and Arthritis.Never are the fingers in each other’s way or will you need to move your fingers to access certain functions (unless you want to use the top two buttons). The large ball rolls smoothly and allows for fast movement across the screen with very small movements. I have the Orbit with Scroll Ring which is excellent but I could use more flexibility with additional buttons. The large trackball of the Expert might feel very heavy at first, but once you get used to it, you will love how accurate and solid it is compared to smaller trackballs. SUMMARY: The Kensington Expert Mouse, one of my favorite trackballs, is now available as a wireless model, aptly named the Kensington Expert Mouse Wireless Trackball.

Kensington actually publicly announced they would not support Win8 because (it was too hard to code for), until they had to cave into consumer pressure.The symmetrical design of the Expert trackball works equally well for both right-handed and left-handed users.
