I bought this device as an adjunct to existing Devolo 200 AVplus devices. Even with this unit commissioning is simple, the transmission quality is exceptional and the firmware is constantly optimized. Unfortunately there are also some criticisms, because the hardware is not nearly as perfectly equipped as the AVplus series: So here lacks a built-in / filtered power outlet, so that the wiring is complex and transmission interference from connected devices are likely. Especially painful is the complete lack of a power-saving circuit: The instrument is always running during normal operation, even if no wireless active and no LAN devices are connected. The long-term operation is significantly more expensive than the equipment AVplus series that have an efficient power-saving circuit. Conclusion: Functional absolutely ok, but not as optimally equipped, as you know it from other Devolo devices.
