The Das Keyboard 4th generation keyboard by Metadot is one of the few mechanical keyboards on the market with N-Key Rollover function via USB. It is specifically designed for high-speed text typing. The Cherry MX Brown switches provide fantastic tactile feedback, with a delicate actuation that doesn't disturb others. Among mechanical keyboards, Das Keyboard 4 boasts the thinnest profile. The volume knob and two high-speed USB 3.0 ports make work even more comfortable and efficient.
