This item was just what I needed, and works perfectly for what I needed.
Having just upgraded to a quicker internet speed, and with the router located some 30m away from a number of our electronic items, I wanted to be able to connect many of them directly to the internet, instead of using a wireless connection, which had a very weak signal, due to the distance.
I already had a network cable running the length of the house, so for me, this really was a case of just "plug-and-play". I used one port to connect the cable running from the router, and connected two other ports to the equipment (a PS3, and our Sattelite receiver). Both were working instantly. And there are still a couple of empty ports available.
This product does come with a UK plug for providing power, so I needed an adapter for using outside UK, but it still works just fine.
For the price, this product is just great.
