Ergonomic split keyboard and mouse

The Kensington Pro Fit Ergo K75406US is a wireless keyboard and mouse set built for office workers who want a neutral hand posture. Its split and sloped layout, adjustable reverse tilt and built-in wrist support are ergonomist-approved to reduce strain during long sessions. The black set connects through dual wireless channels and includes a five-button mouse with forward and back controls.

Dual wireless connectivity and encryption

The kit links via 2.4 GHz and Bluetooth 4.0 with 128-bit AES encryption for secure data transmission. A replaceable receiver means a lost or damaged dongle can be swapped and paired without replacing the whole set. Three-mode power-saving switches and low-battery indicator lights extend usable time between the included two AAA cells for the keyboard and one AA cell for the mouse.

Quiet operation and spill-proof keys

Keys and mouse clicks are designed for quiet typing so shared spaces stay distraction-free. The keyboard is spill-proof, protecting the electronics from accidental liquid contact. Standard F-keys provide shortcuts while caps lock, number lock and scroll lock indicators keep status visible during everyday productivity tasks.
