Professional reviewers and ergonomists agree that finger trackballs are superior to thumb trackballs when it comes to precision and hand comfort. At the same time, professional users prefer the convenience of wireless controllers. Kensington responded with its most advanced trackball ever: the SlimBlade Pro trackball. Now you can enjoy the precision and ease of use of a finger-controlled trackball that supports Bluetooth, 2.4 GHz wireless and wired connectivity, and unique dual-sensor trackball scrolling. All in an elegant housing that saves valuable desk space and can be used with either hand. This means the highest accuracy, comfort and control. Includes a selection of Bluetooth, wireless and wired 2.4 GHz connection options for maximum flexibility. Compatible with Bluetooth LE, 2.4 GHz wireless nano receiver or wired connection. Includes a 2.4 GHz wireless module (USB-A with USB-C to USB-A adapter) and a 1.5 m USB-C to USB-A charging cable (USB-C port on trackball). The battery provides 4 months of battery life on a single charge via the USB-C port. The large 55mm diameter trackball allows users to scroll up and down web pages and documents with high precision with a simple twist. The low-profile shape provides all-day comfort for both right- and left-handed people. The trackball takes up less desk space than needed to operate a mouse and is more comfortable for long-term use because it requires less arm and wrist movement. Dual sensors accurately track the large 55mm ball, giving users improved cursor control that requires fewer hand and wrist movements. Provides highly accurate and responsive cursor tracking and scrolling. Simply connect the USB cable to the trackball and users will be ready to go in no time.
