Having what Logitech calls a "low-profile, framed key design" that refers to the individually separated keys, the K310 allows easy cleaning between all of the buttons. Logitech says that this design delivers "greater accuracy when typing" and we'd have to agree. Comparing typing on the K310 to doing so on keyboards with more condensed key designs, we found we experienced fewer typos and mistakes.
The K310 also features all the shortcut keys you might expect from higher-end keyboards on the market. There are function keys for controlling volume and skipping and pausing tracks, making it that much easier to control all of your media from one place without having to navigate on the screen.
There are also shortcut function keys for email, web search and calculator. These are accessible through the function key, and in our tests were very responsive, working first time every time.
Logitech claims the letters on the keys are laser printed and coated so that they don't fade through heavy usage or due to washing. Apparently, the keys can last up to five million keystrokes. We didn't type long and hard enough to test this claim, but all the keys are still very much intact after day-to-day use for a few weeks as well as a wash under the tap, so we tend to trust Logitech on this one.
One of the few qualms we have with Logitech's washable keyboard is that it has only been made to be compatible with Windows XP, Windows Vista and Windows 7. It might also work with Windows 8, but it has no shortcut or programmable keys especially for Microsoft's new operating system, which we can't help but think might put off some customers.
