Quality product, well finished. Requires a specific driver (Intellikey 6.3 minimum) like any USB keyboard that prohibits its use in basic DOS boot (compared to a standard keyboard PS-2). Otherwise the strike is actually very silent but touched gives the sensation of being on a laptop keyboard, with a run of very small buttons. It surprises at first but soon after we made it! Great integration with Windows XP, since specific buttons (volume control, mute, direct access Calculator, etc ...) are recognized as soon as the driver loaded.
