The K650WP is a membrane keyboard with a PS/2 plug and USB adapter so for those who need to click while they type you may want to skip this review.  For everyone else, the membrane design allowed Zalman to waterproof the keyboard by adding holes to allow spilled liquids to quickly drain away from the keys, as well as coating the aluminium stiffener inside with hydrophobic film and some strategically placed insulation.  TechPowerUp dumped the contents of a 250 mL water bottle into the keyboard to test this feature out and it worked a charm, they only wiped off the keys as the remainder of the liquid drained through the bottom and the keyboard continued to work.  At $27, even if you do manage to damage the keyboard you are not out a lot of money.  Check it out here.

"The Z-Machine K650WP from Zalman is a membrane keyboard that comes in at a price point where there is really no competition from branded mechanical keyboards. At the same time, it offers a waterproof design, dedicated volume-control buttons, and an internal aluminum plate for structural rigidity, making it great value for the money."
