This box is great and we are delighted we made the decision to break away from Sky/Virgin (although we have lost quite a few channels). The box has received so many favourable reviews which is partly what influenced us to buy it, although from some of the comments I was a little nervous that it might be complex to get to grips with. However, IT WAS EASY!!! The picture is much better than our SKY+ box, and navigation/recording etc is straightforward and pretty intuitive. (We haven't found it too different from the Sky remote - and the kids, aged 16 and 13, worked it out without the instructions).
I found some of the tips from previous reviewers especially helpful - well worth a read....the most useful (to me) being:
-use the supplied HDMI cable to link the box to the TV
-unplug the satellite dish cables from your old box straight into the new one
-remember to peel the protective tape off the front
-plug in, switch on and follow the on-screen instructions
There are clearly other things to explore on this box, but the basics - changing channel, pausing, recording, series link are all easy to learn.
