Much's not to write. The set is just to have super cheap at MM. Plugged in, turned and I, without having to draw a cable through the rooms on the laptop in another room a Gbit LAN. I do not understand the technology behind it, but it's awesome all cases !!! I run the set on a Fritz box, so I can not tell if they work as well on a super petrol normal router ?! Great set :) ps .: pay the extra price for a variant with socket: no way ...... what's socket strips XDXDXD
