I have multiroom Sky+HD & when my 12 month contract with Sky ended I took out their Skybox insurance.
I am so glad I did because I started getting problems with 1 of the boxes in February & so far I have had to have 4 replacement boxes fitted & at the moment everything is ok. I am making this point because when you contract with Sky you buy the box,which means of course after your initial 12 months Sky are not responsible for maintaining it,so any problems are down to yourself.Ron.
