This Motorola MB6721 was easy to set up, although it took Xfinity 15 to 20 minutes to recognize it. I have this modem (with an added WiFi router) for just over one month, I have not had any problem with it. It saves me $14 a month of rental fee. I recommend this to any Xfinity cable internet user who is renting the modem from Xfinity with internet speed no more than 600 Mbps.

Easy to use, better value than the Xfinity options, lightweight and potent. This unit is a great deal, seeing how it’s been listed for over $100 in other places.

After a bad experience with a Netgear cable modem, I decided to buy this Motorola model. The purchase was based on reviews I read online. I have had no problems of any kind with it. I’m pleased with the modem. I am using it with a Linksys router model EA7200.

I needed to change the cable modem by switching to a faster internet plan. The previous product sometimes had to be rebooted due to unstable connection, but this Motorola product does not need to. It is very stable and has excellent price-performance.

Not a good Modem. Had slow connection and internet outages. Also realized that it was not able to handle my service speed and features.
