In healthcare, we're always looking for ways to fight cross contamination. Due to these concerns, things that we touch in the day to day treatment of patients need to be cleaned on a regular basis. There are some very nice keyboards on the market that can stand up to the rigors of healthcare and those keyboards are available for about $100. The extra cost is because they are designed and built to be disinfected with some rather harsh materials.
I'm not sure that the Logitach Washable Keyboard K310 would stand up to those types of rigors. The website states : * Hand wash only. Use mild soap and a soft cloth in warm water less than 30cm (11 inches) deep and less than 50°C (120°F). Do not wash in dishwasher. Do not use abrasives, alcohol, solvents or harsh detergents. Do not submerge the USB cable. Follow washing instructions in the Quick Start Guide.
So… this might be something that is better used in non-clinical areas or covered with a barrier and then washed on a regular basis. The part that I find really intriguing is the price of $39.99 which is amazing for a device that can be immersed in water.
