Currently on BBYW Pro and it seems to be very good. The support is very quick and efficient and my broadband connection fully maxes out. Each tariff has clear information on expected speeds with the traffic shaping, which is very clear before signing up. That being said no one can complain for being throttled as its made very clear to you. Its a very fast service and i enjoy the community, and as an added bonus the new usage allowances make it that little bit better. A lot better than my old provider (Surfanytime) who were very incompetent and unreliable.
