Product Information

To Esther above (Although you probably will never see this follow up) I am using my Kensington Expert Wireless Trackball on two different devices, a Macbook laptop and a Desktop Linux PC.

To help the connection of your appliance go smoothly, please watch our dishwasher or washing machine connection video. I did have trouble when one of the buttons got a little shaving of plastic caught under it, and in trying to extract it without disassembling it (four Philips screws in the base) so I didn’t void the warranty, I accidentally twisted the button. These issues are endemic to all trackballs, not just the Expert Mouse Wireless, so I'm not criticizing Kensington here.All Trackball Reviews • Compare Trackballs • Trackball Top 10 • Affiliate Disclosure • About TrackballMouse. Expert Mouse Wireless Trackball is comfortable to navigate, and compact enough to suppress strenuous motions. There's even a storage slot for the Wi-Fi dongle should you ever need to take the trackball on the road.

The left button definitely got worn after two years or so, but it’s just cosmetic – the glitter coating is only a couple of microns thick. These clean high quality materials are then sent directly to our recycling partner so they can be put back into the raw material streams. It appears that Kensington in their wisdom wanted to have it moving in small steps so they introduced a magnet. The Kensington Expert Wireless Trackball comes with a detachable wrist rest, two AA batteries and a wireless USB 2.It is like a 4-port USB Hub that connects to two different machines, and it has a switch to choose which machine you want to use. As mentioned earlier, the only other trackball that offers a ball this big is the Kensington SlimBlade ( update: the CST also has large ball as well as the Elecom HUGE).
