I ordered this key at the base Bluetooth to play with my ps3 controller on pc but it appears that this does not work so good I say too bad for my bluetooth work ca pregnant the first apparatus nickel everything works. I put the computer on standby, and the back on its not working anymore so I re unit still nothing. You must restart the computer and then rappareiller for his time running a session in which case if you put the PC in standby it will be lost.
