Looks great on my Keychron Q5 (1800 with a knob) w Gateron G Pro Brown switches. Unfortunately, Keychron Q5 1800 has a slightly smaller alt, fn and ctrl keys and larger + key on the right side so had to use the original Keychron keycaps for those keys. So anyone planning to buy Red Samurai keycaps for Keychron Q5 1800, buy the base kit w extra nishi and novelties instead - costs more but then you don't have any missing keycaps.
