Manufacturer description
The Kensington SlimBlade Pro Wireless Trackball (K72085WW) is a finger-operated trackball built for people who want precision without the arm sweep a mouse demands. A 55mm ball sits at the center, tracked by dual sensors that also enable Kensington's ball-twist scrolling, so you scroll by rotating the ball rather than reaching for a wheel. You get three connection paths: Bluetooth (BT4.0/BT5.0), a 2.4GHz USB-A dongle with a USB-C adapter, and wired operation over the included 1.5m USB-C to USB-A cable. The rechargeable battery runs about four months per charge, topped up through the…

Frequently Asked Questions
How does the Kensington SlimBlade Pro connect to a computer?
Three ways: Bluetooth (BT4.0 or BT5.0), a 2.4GHz wireless dongle (USB-A, with a USB-C to USB-A adapter in the box), or wired using the included 1.5m USB-C to USB-A cable.
How long does the battery last between charges?
Kensington rates the rechargeable battery at 4 months of use per full charge. It recharges through the USB-C port on the trackball, and you can keep working wired while it charges.
Is the SlimBlade Pro suitable for left-handed users?
Yes. The low-profile shape is symmetrical and Kensington specifies it for both right-handed and left-handed use, so you do not need a separate left-handed model.
How do you scroll on this trackball?
You twist the 55mm ball itself. Dual sensors read the ball's rotation for scrolling as well as cursor movement, so there is no separate scroll wheel or ring to reach for.
Can the buttons be reprogrammed?
Yes. The free downloadable KensingtonWorks software assigns program functions to 8 sets of programmable buttons, which requires KensingtonKonnect installed.
