It's a well known "scientific fact" that dirty language leads to dirty input devices, and the people at Logitech have zero-tolerance for dirty keyboards. The result of intense rocket-scientist research is the K310 washable keyboard that can be submerged in water up to 11-inches in depth, at temperatures up to 120-degrees Fahrenheit. That's possible because of "rubberdome key technology".
Drainage holes at the back of the K310 remove the water and debris from spilled foods and beverages, while the laser printing and UV coating on the keys make it durable so the keys will not fade. The unit is plug-and-play and works right out of the box with no software to install.
The Logitech K310 is scratch resistant and tough, but not invincible, and is definitely not intended to be placed in a dishwasher. Another cautionary note is that the USB cable must never be submerged in liquid.
The layout is familiar to all, with F-keys and a number pad, and even 12 hot keys. Logitech claims the keys are rated to last for 5-million keystrokes. The color combination is a classy combination of white keys on a black background, and the typically unseen underside of the unit is blue. The 3-year warranty provides assurance of performance.
