He didn't really go into that though. He looked at features, not materials or build quality, which are both major factors in mechanical keyboards. I can tell you first-hand that the materials that Logitech, Cooler Master, and Corsair use on those particular keyboards don't compare to anything that WASD uses; the K60 isn't even completely mechanical! Those are all "budget" mechanical keyboards. The Filco is more comparable, but at the same price and without backlighting or MX Clears.
