I bought this keyboard two months ago because I really love cherry mx clear switches. The first thing I noticed after a couple of minutes typing with it is the know ping noise. Each time you press a key, there was a piece of metal under the hood that echo like if you bend it and then it took it original form. At elitekeyboard, they told me it's a normal sound. The problem is I already have a keyboard with cherry mx clear from truly Ergonomic keyboard and there is no noise...
