Kensington’s new version of its SlimBlade trackball mouse has a big improvement over the original model: wireless connectivity. With the SlimBlade Pro, which Kensington announced, you’ll be able to connect the trackball to your PC or Mac via Bluetooth or with a 2.4GHz wireless dongle. Kensington claims the SlimBlade Pro will be able to get up to four months of battery life on a single charge, so you should be able to use the trackball for quite a while before needing to plug it in. The dongle has a handy storage spot on the bottom of the trackball if you want to keep it out of sight. And if you prefer keeping your mouse or trackball hooked up to your computer all the time, the SlimBlade Pro works with a wired connection, too, thanks to a built-in USB-C port. The SlimBlade Pro otherwise offers many features available on the original SlimBlade. You’ll also be able to customise what each button does with the KensingtonWorks software, which could be a useful way to personalise the mouse for your needs.
