Has anybody used this service?

I emailed to check if valid subscriptions to Sky/BT were required, they said no - it was all included in the yearly subscription to them.

I then emailed and asked about their returns policy in case it didn't work as expected and got no response, which has made me wary.

It would be greatly appreciated if anyone has any feedback regarding this service. It ticks most of my boxes but I don't want to be ripped off if it doesn't deliver what it says on the box.
