The Excalibur RGB mechanical gaming keyboard is the successor to the original Excalibur mechanical gaming keyboard and as the name clearly reveals their main difference is the full 6-level RGB (16.8m) backlighting for the keys. As for the rest well the Excalibur RGB features mechanical switches by Kailh (available in brown, blue, black and red) and also packs a number of features including programmable keys, 6-Key/N-Key rollover, gaming mode, macro commands and the ability to store up to 5 profiles in its 512Kb of onboard memory.
