For anyone who is having problems using "auto" HDMI switches with automation systems, this device has manual switching. You select the input and it stays selected. Anything done to other connected devices have no effect. That is when select mode is chosen. My system is unusual and controlled with Harmony system. Before changing inputs was 50-50 chance of working. In manual mode and the automation is rock solid. I have spend much $$ and rotated through several devices before finding one that worked.

Overall, it does exactly what I need at this moment, plus apparently all kinds of cool sounding things I don't necessarily need right now but might down the road.
