Ordered this and it arrived quickly. Make sure you order some co-axial cable to run from the main sky box to the room you want to watch sky in. The hardest part of setting it up was drilling the hole in the wall.
When I first got it set up, the second tv was receiving a sky signal but I couldnt change channels using the sky link (the red light on the sky link was not on). Apparantly the middle bit of the cable is was passes the sky signal and in this case was working fine. However, the outer metal part of the cable is what passes the power to the sky link unit. I had just cut everything off the cable minus the middle bit and connected. I soon sorted it by sripping a bit more off the cable and making sure the outer metal part was connecting to the metal co-ax connectors and hey presto, all worked fine.
Great little device for watching and controlling sky from another room.
