Manufacturer description
The Kensington SlimBlade Pro Wireless Trackball (K72080WW) is a finger-operated trackball built for people who want precision without the arm and wrist travel a mouse demands. Its 55mm ball is read by dual sensors, which handle both cursor tracking and Kensington's ball-twist scrolling, so you scroll by rotating the ball instead of reaching for a separate wheel. The rechargeable battery runs about four months per charge over USB-C. The low-profile, symmetrical shell works for right- and left-handed users, and the SlimBlade Pro takes up less desk space than a mouse needs to move. Free…

Frequently Asked Questions
Can I use the SlimBlade Pro without the wireless dongle?
Yes. It pairs over Bluetooth 4.0 or 5.0, and you can also plug it in and run it 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 about 4 months of use per single charge. You recharge through the USB-C port on the trackball itself.
Is this trackball left-handed friendly?
Yes. The low-profile shape is symmetrical and Kensington states it supports all-day comfort for both right-handed and left-handed users.
How does scrolling work on a trackball with no wheel?
You twist the 55mm ball. Dual sensors track the ball for both cursor movement and ball-twist scrolling, so no separate scroll wheel is needed.
Will it work with a Windows on ARM laptop?
Kensington notes that Windows ARM-based computers are not currently supported by the KensingtonKonnect software. Check the product listing for updated compatibility.
