I don't know whether it could be classed as bad luck my friend - The links that I posted show a worrying (IMHO) number of manufacturer refurbs - now don't get me wrong if I go and spend £30 / $30 on a keyboard - my expectations regarding quality, durability, reliability and generally not...
From my own personal perspective - I feel that they are pants - I have had 2 of their mechanical keyboards die on me in quick succession - the 2nd one I just binned after it started failing. Sour grapes?
Well this I think adds some substance to my statement...
