The Devolo makes a robust impression and doing what it should, but this makes my tests after no better than the often günstiere competition. We have some people in the house LED that have significantly limited the transmission rates. I have hoped for improvement of the promises of the Devolo adapter and so our 30-EUR units have been replaced by Devolo starter set and now extended by this additional device. Unfortunately, this change brought zero improvement in terms of bandwidth or Ping.
