Customers are saying

Customers are positive about the product's impressive speed, strong performance, and overall ease of use, including its simple setup and seamless connection. They also appreciate its compatibility, DOCSIS 3.1 support, and affordable price, noting that it operates without lag and stays cool. However, customers are negative about the limited number of ethernet ports and, for some, the signal strength.

    Basically flawless. Easy to install. It will pay for itself in a year by not having to pay a monthly rental charge from the provider.

    Appears to be a high-quality device, but still having issues with WiFi connectivity; which I believe is the fault of our service provider. However, when WiFi is on, this is a fast system

    Xfinity tech support always takes forever to enable user owned equipment -- but when it is done -- it just works. Unit itself supports top download speeds and works great paired to a wifi router like those from Apple.
