You can now drink your beverage of choice at your desk while keeping your peace of mind. The Logitech Washable Keyboard K310 has overwhelmingly positive user reviews on Amazon for its durability and design. Users report that it survived coffee, soda, water, and soap. It can be hand washed and submerged in up to 11 inches of water. The K310 is equipped with drainage holes for fast drying and comes with a keyboard brush for dusting and scrubbing. Just leave it in a drying rack overnight to air dry.
While most waterproof keyboards are made out of a soft, clumsy rubber, the K310 looks and responds like a conventional keyboard. Its keys are laser printed and UV coated so that they will maintain their form after many washes. Far from clunky, the K310 is a slim .8″ by 17.2″ by 5.5.” It weighs 17.3 ounces, making it fairly lightweight for a keyboard.
The K310 is a USB keyboard and is ready to go as soon as it is plugged in without any driver updates. It features 12 programmable shortcut hotkeys that can take you directly to the Internet, email, volume control, pause, sleep, play and more.
The Logitech Washable Keyboard K310 is available at Amazon for around $79.
The Kensington K64406 Washable Keyboard is another spill-proof keyboard at a more affordable price tag. Reviewers on Amazon did notice a sacrifice in design and functionality, however. It is available for around $27.
