Just costar reference designs and they slapped a logo on it, nothing special. Fullsize is based same thing as Mionix Zibal, Tt Meka G1, Ozone Strike (old version), WASD (old version), etc. The tenkeyless appears to have more in common with the Filco MJ design, whether any cost cutting employed internally... who knows?
Definitely nothing in common with Max Nighthawk, which is an iOne reference design based model.
