Used home on a WiiU and a PS4, this device works perfectly. It automatically chooses the active signal. If all are, it is the last device to be a priority. In such cases, the remote control or button on the device used to manually select the signal.
Little detail can be annoying: the blue LEDs on the case are too bright and can be annoying in the dark. The ideal is to hide the box in a cabinet or behind a camera.
