lal, it's membrane. do not expect too much for boards with windows keys unless you know the board is with Cherry MX.
re Futaba switch
It's actually a mechanical switch. You will get strange( or should I say *unpleasant* ) feel with it. You'll get faint tactile feel, and then shortly after tactile feel, clicking ( distracting clanky/klangy/echoey noise as skriefal described ) comes with upwarding a key. I evaluate the switch as " too much self-assertion, lacks Gracefullness"
