    Great Modem

    I ordered this on line second hand and it was easy to set up. I just used the cords from the modem that I already was using from the rented modem I had and hooked them to this modem. I had to call my cable service to give them my new modem number but then I was all set and it works great! I no longer pay for a leased modem each month and the price was great. I am a very happy customer.

    Returned my old Cable modem to my internet provider. I am happy with the modem. Slightly faster than older modem, fast set up, and so far reliable.

    Great buy

    This was delivered literally in 2 days and was at my home by 5pm witch was epic because i just moved into my new house but the only sad thing was it didn't include the Coaxial cord but that wasn't bad still with that great price.
