Not bad but I've only been on it since just after Christmas. It's ADSL 2+, which means I was getting roughly 1MB/s more on the line than I was with my previous provider. However the ADSL router they gave me is not very reliable, seems to crash about once a day and my old router is only straight ADSL so I lose the extra speed if I want reliability.
I also suspect that if I phone the helpline about it they will want to to install that Broadband assistant app thing, which I have absolutely no intention of doing

. So I'll see how I get on with the modem and if it is permanently dodgy I'll chuck it out and get a decent one from Dabs or something.
That is one big plus for them actually, that they're perfectly happy for you to plug your own kit into the line. As oppose the likes of Sky or TalkTalk who insist on giving you a router that's so locked down as to be, for someone technical like me who wants to do some odd things, utterly useless.
