The performance increase over my getting on in years Devolo adapters "High Speed 85" is was significantly lower than expected. Real practical (and reason for buying) were the two RJ45 connectors instead of one. Design has become more chic and even flatter.
However, the adapter gave very unpleasant noises. Since I had placed a behind a cupboard and not every night can pull the plug, I was the beeping and screaming too much -> return.
