Customer Reviews for Internet Service Providers in Colorado
Customer Reviews
A Westminster, CO Customer
Quantum Fiber
August 14, 2025 When it works the internet works great. The price for speed cannot be beat. The downfall of the provider is their customer service and equipment. Their router/modem setup always drops my connection. Searching the web this is a common issue that others have and end up having to pay more to use 3rd party devices. Contacting customer service does not resolve the issue.

XFINITY Cable
July 01, 2025 I’ve been using Xfinity internet for over 20 years now and the experience has been consistently reliable. The speeds are fast and stable, even with multiple devices streaming, working, at the same time. Setup was simple, and the technician was professional and helpful. I really appreciate the ability to manage my account and settings easily through the Xfinity app. Customer service has also been responsive the few times I had questions. The pricing feels fair for the speed and service I receive. Overall, I’m very satisfied with Xfinity and would definitely recommend it to friends and family.
