Instant installation, comfortable speed, application in Fr, possible setting for max security. In my configuration villa, no Wifi only fonctionnai between floors (floor, walls, concrete stairs etc etc ..) CPL solution is really the solution. BONUS: I have a three-phase installation, and by chance the two PLC adapters are in two different phases, unlike various reservations made by internet users it works perfectly despite this, it rocked. No not with the two multiple sockets problem (like 1 + 2 and 1 + 5 with inter). Simple and excellent product.
