I got it in December.
Its like everything with SKY, its really good until it goes wrong! a mate of mine bought it around the same time as me and his box has just packed up and hes lost everything he had saved. I've heard people have set things up to tape and its recorded other things instead
Saying that, I've not had any problems with it apart from exiting back to live tv after pausing its hung a couple of times, nothing major.
