I know its frowned upon to give an isp perfect 10\'s but ive had 0 issues since i migrated just over a week ago, the migration date was spot on however this is i believe determined by BT (the less said the better about them nudge nudge etc)

1) service, i called them before i migrated, they were prompt and friendly no BS

2) Support, in all honesty ive had no issues but ive seen them help many users on the forum

3) Speed, as fast as it should be! no traffic shaping or port throttling at all

4) Cost, its not cheap, but why give it 10 stars then? for exactly that reason, you get what you pay for!
