We switched ISPs when we moved to Texas, and the only complaint is that it took 2 weeks after we moved here to get hooked up. Other than that, the installer did a nice job of putting in the required hardware and so far we are happy with the service.
The service is great. But, the wait for installs and repairs can be lengthy. We grabbed the repairman's contact info. He was able to push an appointment up. We have been at the new place for almost a month and they still have not come out to bury the new lines that they installed, even after follow up phone calls. Bottom line: The service itself is great for the cable and internet. But, long wait for appointments.
