    Easy to install and well worth my investment. I was referred to this by a customer service rep at the local cable company. Great referral for my desired upgrade.

    Great modem for comcast/xfinity. Extremely easy to set up. I was up and running in about ten minutes. It would have been quicker, but I had to wait for comcast to address it(automated phone systems take longer).

    I have had zero issues with the device. Works with my router, and i have at least 20 devices connected at a given time. Nothing lags, drops, or gives any issues. Modem has yet to be extremely warm when touched.

    Had a problem with internet dropping out and BB Associate sold me on this modem coupled with two new modems to reach to needed areas in a 4000sf four story home. It's working well and have had no problems.

    Works great easy to set up. Fells good to get rid of Spectrum modem. Spectrum didn't make it easy to switch, but with a little tweaking got it to work.

    I purchased this external hard drive because it offered a ton of space for a great price. Allows me to backup all files, movies, music, TV shows, and pictures. All the space I needed and more to spare.

    I use this monitor for photo editing and the color is almost true to printed photos. I also love the curved display because it reduces glare and sleekness of the design! Highly recommend this product!

    Had to upgrade from our previous Motorola modem that never gave us any troubles to this newer model to stay current with our cable provider. Great service so far with no issues in the first few months.

    I had old Motorola - DOCSIS 2.0 cable modem for many years and I decided to pick the same Motorola - DOCSIS 3.0. It was easy to setup and don't forget to reboot your wireless router as part of the install.

    Very pleased with purchase. Read that some were having issues with their modems not working well for Comcast cable and high speed internet in rural areas, but this one has been perfect.

    I purchased this modem for my daughter because she was having problems with Spectrum modem. This modem has done the job for her. Purchased it for $20 off price which was a plus. No interference in service so far like she experienced with provided modem.

    It works very well for what we need. We use cable to stream videos, play games, and listen to music. We have at most 4-5 electronics utilizing the internet at a time.
