    Automatic and Manual

    Overall: 3 out of 5

    This switch works well , Turn on a device and it switches to that device .
    Turn off a device and it switches back to the device that's still on
    Or you can push the button and manually switch between devices .
    The photos of this thing make it seem bigger than it is. It's tiny

    Exactly what it is supposed to be.

    Overall: 5 out of 5

    I've had this unit for several months now and it does what it is supposed to perfectly. I have an Xbox 360, a Blu-Ray player, and a steaming media player all plugged in and only have to tie up one HDMI port. I recommend this to anyone who has more devices than ports on their TV.
