Have the first unit sent back because loose connection to the power supply. The supplied replacement device in this regard without errors. Installation went smoothly, here there is nothing to complain about. Unfortunately, in my work, not all devices that are "hidden" in a Lowboard. So my two Yamaha devices (AV receiver RXV 771 and Yamaha BD-S673 Blurayplayer) are not driven while the cable Germany Festplattenreceiver and the Apple TV box functioned without problems. I kept the part anyway, because I can control the Yamaha devices via WLAN. Due to the limited device compatibility only 3 stars.
