Get this and save on reoccuring rental fees!!!
Works with Xfinity and after hooking up you'll need to go to your Xfinity account and activate it! Xfinity doesn't make it easy to find the activation since you're taking away $15 a month they'd love to charge you to rent one of theirs! LoL, what a joke right!

Reliable and fast enough for our needs.
Product arrived quickly and has been working flawlessly for a month now. I was cognizant that it is a DOCSIS 3.0 cable modem, not DOCSIS 3.1. However, based on my research and the speed of our internet connection, its performance is way above our needs. Why pay for a newer and faster router when you know that you won't use the super fast connectivity. We are using the router with Comcast and it has been rock solid. The old cable modem (also DOCSIS 3.0 but 8 year old model) was showing more and more errors. Since I swapped with the new cable modem, no errors. Just a nice stable connection.

Happy With It!
Previous modem started to have reliability problems, so I tried this. Had it running for over a week now, and setup was easy (followed my ISP's [Suddenlink] online instructions) and had it up and running in minutes. I have a contracted download speed of 400Mbits, but usually received actual speeds in the 200 Mbits range. Both of our desktops are hard-wired to our router. In my experience, different browsers and computers can make speeds vary. But on my machine, Firefox went from 294.7 with old modem to 322.4 with this Motorola. On my wife's machine, Chrome went from 145.3 with old to 202.9 with this modem. Opera, Edge, and Yandex browsers were all in the range of what they were before, on either modem. My old Acer Chromebook (which is connected via WiFi) was always slow with the old modem (50Mbits or so), but increased a bit with this new modem (60.6Mbits). I'm happy with the performance of the Motorola and besides our desktops, we have Roku and Firestick streaming devices, as well as tablets and e-readers, so pretty heavy Net users. Last two modems had Intel chip sets, and while it didn't make a difference to me, I started to read about the Intel/Puma chip set problems (easy to find with a online search), and started to wonder if the problems with my old modem were somehow related? (Could never prove it...) But this Motorola has a Broadcom chip set, so I thought I'd err on the side of discretion. This modem gets good reviews everywhere I checked, so I chose it. Happy so far!
