I've been very very happy with Shaw over the last five years. This is, in part, because of their awesome student discount. Getting cable, internet, and phone at a discounted rate is a huge draw for any person on a budget, and Shaw has really catered to student users by providing it.
When something on my system doesn't work, Shaw is always good about fixing it in a timely manner. This is important to me as it means that they get my cable and internet back up and running. As a student, I often need internet access for my research--having shaw quickly fix what I've needed is imperative to my work.
I will continue to use Shaw for my cable service in the years to come, and am pleased with how quickly they work to fix any issues we have.
