My latest review is of the Kensington Slimblade Pro Trackball.

I’ve been a Kensington customer for over 30 years. You’ll see my Apple IIgs trackball in the video from 1988 or so! This new one has a similar footprint but of course is much more modern.

The trackball uses an optical tracking system vs. rollers to gauge the position of the ball. It’s also wireless and can be used via Bluetooth or its included 2.4ghz dongle that garages itself on the bottom of the unit. It can also operate directly connected to a device via its USB-C port although those who are looking for a direct connection may want to look at the slightly less expensive non-pro version that retains most of the feature set here. The Pro edition also has a DPI setting that can adjust the sensitivity of the tracking on the fly.

What I found most innovative about its design is its nifty “twist to scroll” feature. Twisting the ball will scroll the active screen up and down. When twisting the mouse makes a clicking sound to differentiate it from its regular tracking mode. It very seamlessly switches from pointing to scrolling in use.

On the Mac and Windows there is a configuration software called “Kensington Works” that allows for some customization features with its four buttons. One of the neat ones is an option to lock in the x or y axis of the mouse to help draw straight lines up and down.

All in this feels like another solid Kensington mouse which is no surprise given they’ve been at this now for decades.

Disclosure: The Slimblade Pro was provided free of charge from Kensington for this review. I also produce informational videos for Kensington as a compensated consultant on occasion.
