I have it and have had no problems at all. It's cheap, quick and easy peasy to set up at home, a piece of cake to be honest.
Speeds are around 8 or 9mg, once hit 10 but averages out around 8 and a bit.
It took about four days to change over and that was no problem too. Only issue there was being on the phone to BT for 45 mins whilst he tried to talk me out of it before he gave me the MAC code.
Go for it, it is not a bad deal at all.
