    I was excited to install this, but realized it wouldn't work with comcast voice/phone line. Unfortunately, I waited too long and I couldn't return it. Make sure you read the box, know what you are buying and don't rely on the sales guy to pick out what you need.

    Bought this as an inexpensive alternative to renting from the cable company. Unfortunately, didn't initially realize that it doesn't include the hardware to handle the telephone line as well. If you don't have a land-line it's probably fine. We returned it unopened.
