In principle, the devices are ok. Initially, the connection was stable and fast. After a few weeks we went wrong with occasional dropouts. The compound was quickly rebuilt. The terminations accumulated over time and became longer, until finally after about 2-3 months was the end when a connection ends. No connection could be set up more. Reset, insert new etc. did not help. If the adapter fell from even the LEDs. Device was then replaced by amazon. The same procedure was repeated. This time without LED failure, but the same disconnections. All Powerline rules have been followed. Am now in much more expensive Devolo landed product. Makes a very good impression so far ... let's see what time brings.
