I bought this product to equip Wifi part of the house too far from the router and especially separated by very thick walls. Despite a power grid a little old (30 years), it fontionne very well and the flow is very good. Product very easy to implement: just plug it in! Only regret that the LC / Wifi module does not not have a filtered socket, which would avoid monopolizing a wall outlet (which is why I put only 4 stars).
