This is a wonderful item and saved me a lot of money. I bought a new internet enabled TV and a new Sky HD 1TB box. My router is in another room and to buy the suppliers' dongles to connect both boxes would have have cost about £150. Instead, I bought the TP-Link TL-PA211KIT 200Mbps Mini Powerline Ethernet Adapter - Twin Pack
and this little box here (£8.65 at the time) and connected them up. And Hey! It worked first time. Saved over £100 and then I did the same thing in another room, except this time I only had to buy a TP-Link TL-PA211 200Mbps Mini Powerline Ethernet Adapter - Single Pack
(£21 at the time) and this again saved me over £100. Wonderful. Please note I am not a Techie - all I had to do was connect a few pieces of kit into sockets (the power sockets were all UK sockets). I would recommend this to anyone wanting to connect a TV or a sky box to to the internet.
