Finding myself with 3 devices to an HDMI port, this device is very useful. Just set for your devices a 3 order of importance (profile: decoder blueray and console). My decoder being constantly connected, I put down important list. If I want to take a blue-ray, ignition of the reader, it automatically switche above. Qd I cut, it is the decoder. If all devices are switched on simultaneously and that I do want to go back to the decoder, no worries, a small button lets you toggle-or even on different ports. The only downside is that the blue LED diode in the dark is light enough, but just hide it.
