I have the BlackWidow Ultimate Stealth 2014 edition. After a year and a half of using it, I'm not seeing any fingerprints on the keys or base, but maybe I'm missing it. My keyboard is a defect one anyway, it has two "M4" keys.
Build quality is pretty good, but the only reason I even ended up going with this keyboard was for the macro capability. Then I found out how terrible the software was for it, and how you CAN'T use any of the advanced functionality without the software. So, I'm not sure what I'll do next time. Hopefully this one will last to its acceptable lifespan.
My point is who are they targeting with this? Macro keys are INSANELY useful if you are doing any sort of more-than-casual gaming, if not just to take the tedium out of certain actions you perform routinely. And making a gaming keybaord that doesn't really appeal to gamers seems... strange.
