    • Quit paying the cable companies

      This modem works very well and has enough ports to connect every component I have. Paid for itself in 7 months by eliminating cable charge for the company provided modem.

    • Does what it is suppose to do....

      I'm using the Motorola SURFboard SB6121 Cable Modem instead of renting a cable modem from Comcast (yes, this is an Comcast approved modem). My speeds from Comcast are the same if not a little better with this modem.

    • Stopped paying for rental modem

      At a lower price than retail, this has turned out to be a great buy. I think the data transfer is quicker than the rental unit. A wireless router needs to be purchased separately. This is an approved device for Time Warner Cable.

    • Comcast compatible

      What can I say? Easy to install, took just a few minutes on the phone with Comcast to get it activated and saves me rental fees. I'm happy.
