I don't have Charter as they are not in my region but I have a similar provider called Cox Communications which is also a coax/fiber provider. Are you just looking to hear about their overall service quality and customer support? If so, even though they are in various parts of the US, feedback may differ from region to region so I would try to find local opinions/rating if at all possible. Here is one example from Yelp: http://www.yelp.com/biz/charter-comm...#query:charter.

You may be able to do a broader search for their customer service however as most likely you'll be calling into a call center on the other side of the nation even though local installers/technicians will be locally dispatched.

We just have internet services and video with 3 DVR's, using our cell phones for any calls but I've been looking to 'cut the cord' very soon for our video services. I've got Netflix as well as Amazon Prime so it should be a smooth transition. I also have an amplified HD antenna that picks up around 20 stations including local news.
