The Kensington Pro Fit Ergo TB550 Trackball (K72196WW) is a wireless alternative to a conventional mouse: control the cursor with your thumb without moving the device across the desk. Connect via Bluetooth Low Energy or 2.4 GHz wireless; a USB-A nano receiver for the 2.4 GHz connection is included.
Its 34 mm ball works with an optical sensor offering four selectable cursor speeds: 400, 800, 1200 or 1600 DPI. The built-in ejection button lets you remove the ball for cleaning. A sculpted body with a 45° tilt and a 4D scroll wheel supporting vertical and horizontal scrolling provide different ways to position and navigate on screen.
The rechargeable battery is specified for up to 4 months of operation from one charge. At least 51% by weight of the plastic components use post-consumer recycled content; this excludes the circuit board assembly, battery and charging cable.
Package contents: USB-A nano receiver.
