I needed a device to receive TV signal in a room and avoid having to pull an unsightly cable between my living room and the bedroom. This PLC technology seemed to respond to my problem and I have not been disappointed. Of course, the box with only two adapters can connect only one position, but it is enough. Everything works smoothly for now. The planned cable are too short because the adapter being mounted on a wall outlet (to maintain good quality signal), it is necessary to install the receiver near, which is not always obvious. Overall I am however very pleased especially since the implementation is not too complicated. The price meanwhile is quite reasonable. A good acquisition.
