Small discount but mainly as was looking for a Cherry MX Brown switch keyboard and everything was so overpriced, but ordered this and actually was extremely impressed with build quality and tactile feel. I've got a Logitech G910, Fnatic Gear MX Brown and Corsair K70 MX Browns and these slot right in with the equivalent Cherry keyboards and much better feel than the Romer-G in the Logitechs. For this price which is what you often find the 'gaming' membrane keyboards, I think it's a steal. Plus aluminium front side gives it a quality look.
