These frequent reports of failing switches on new Filcos are getting suspicious. I've never heard anything like that about Cherry-made boards. I wonder where they manufacture switches for Taiwan.
How many geekhackers have Cherry corp. boards with blues for comparison? Scorpius reviews are a litany of bad blue switch stories, and I've heard of dull switche on DKs as well. Let's put it this way; Diatec did not want to carry blues for precisely this reason, they now carry them again because I order them (At geekhackers' request!)
It's a complicated switch mechanism.
To deal with this, all blue boards that leave EK are tested to make sure every key clicks. E-mail us if you receive a board that doesn't perform to this standard.
