Yes, I've been very happy with the dial-up service. There was a period, not long after it went totally free I think, that it would be a nightmare to connect to, some evening would take 15-20 attempts!!!
Mine normally connects at 50.6K, but now & then goes up to a super 52K

Now & then it will connect at something like 36K, get confused & disconnect itself
But I am so close to getting 600K BB, I really really want it, just trying to convince myself its worth the extra £15 a month!
