Finally, there exists an amazing mechanical keyswitch keyboard without the noise normally associated with mechanical keyboards! The Quiet Pro Keyboard uses Matias" new Quiet Click mechanical keyswitches, which were over 2 years in the making. They deliver a feel that is unmatched for comfort, without sacrificing the tactile feedback you need to type really fast. Also includes 3 port USB 2.0 hub, special anti-ghosting circuitry so that the keyboard keeps up with the fastest typists, laser etched keys so the characters don"t wear off, and traditional sculpted keytops for comfort and speed.
