Note: Advantage keyboards are not compatible with most Windows 7 computers which have USB 3.0 ports, even if they also have USB 2.0. This problem doesn’t happen with other operating systems, such as Windows 8, Mac & Linux. This drop is limited to 150 units.

Additional Note: At checkout you have an option to choose between the Advantage in QWERTY, Advantage in QWERTY/DVORAK (+$25), and Advantage LF in Cherry MX Reds (+$25). Also, there is a PS/2 conversion kit (+$25) available as an add-on.
