Speeds are good. Reliability is good. Customer services is only passable. I own my modem, rather than rent. It's more cost-effective for me. I received an e-mail from Comcast informing me that I needed to upgrade to a new modem. When I called to register my new modem, my call was disconnected several times and had to keep calling back. The only way the system would stop disconnecting me was when I agreed to complete the survey after the call was over. I love the Internet service, but hate the company.
