Duck is one of the biggest and prominent keyboard designers from South Korea. Bold with his experimentation of unique keyboard layouts, Duck brought to market the first 96key keyboard and his current Lightsaver V3 is the best in its class. While the compactness of the layout may make the keyboard appear large, this keyboard in fact shares the same footprint as any standard TKL keyboard. With the VIM accent keycaps, the GMK Terminal keycap set is a great set for anyone using this board to do some serious work while looking for a compact form factor.
