I've had RoadRunner for a few months (Time Warner, Southern California). The service has been good, with few major issue, that I could attribute to RoadRunner anyway. The installer was very helpful, but they insisted that some dumb rule in the book required the installation of a new drop line to our house in a different location, which I did not appreciate one bit. Tech support was helpful without a long wait, the one time I used them. Customer service is another matter. They screwed up my first billing royally, double-charging me for services I did not buy. It was a pain to straighten out, and even now I'm not convinced that is has been completely. You deal with big companies, this is what you get, I guess.
