    My second Motorola modem and am very happy with it. Plenty of speed (nearly 500mbps down) and more space if your service is faster.

    Gets the job done as described. I'm not a high bandwidth user. This modem is stable and almost never needs a reset. Even in power outages it comes online without needing a reset. At the end of the day it does exactly what I expect from a cable modem...quietly sit in the corner while I forget it exists.

    Easy to install. A little configuration with the cable company as they want you to rent theirs, which is the same model.

    Not the top model in the Motorola line but performs just as well, and, for a lot less money

    I love this modem, so easy to set up. Before you purchase, make sure your ISP supports it. Had no issues with Cox.

    All it claims to be, plus a physical off switch

    We had been paying for 300Mbps download speeds from our ISP, but had been stuck with 100Mbps from our former modem. This product has us ready for the future with 1Gbps transfer speeds (if we ever decide we need that much throughput). I've gotta say, as the IT person for our household, I love this product. It has <gasp> an actual off switch (rather than unplugging the thing in the result of an issue). It gets two enthusiastic thumbs up from me.
