Reliable parts for the domestic home network

Of these devolo I have three in my house in operation, as well as various other simple 500. Only one of these parts has -glücklicherweise yet "adopted" in the Garantiezeit- and was replaced without difficulty.
For me, the parts have never been any noises or have become too hot. Actual speeds have nothing to do with the maximum speed, which is also due to various factors but. I can in any case without problems - such as Ruckler- stream movies.
Therefore, I am satisfied with the devolo and forgive all five stars.
