Just bought a new Filco Majestouch 2 Ninja Brown switch at RM399. The big keys like the Shift, Backspace, Enter and three big keys at Numlock sort of rattle when I lightly tap them (not press, lightly tap). Is it normal?

Anyway, don't know if it's the right place, but does anybody here know where to get keyboard trays?

Huh, that confirms what I've heard about Filco thus far. It does get annoying though since whenever I tap the Backspace button, I can hear the rattling sound.

Keyboard tray refers to those sliding out surfaces normally on computer tables. (https://imgur.com/a/d79zg#0)

finally i got my CMstorm mechanical keyboard 

but i got a question is the keycap standard?
