November 11, 2026 Verizon is hands down the worst company I’ve ever had to deal with. Their service is shit, the prices are obscene and their customer service couldn’t possibly be more useless than it is

Crossroads Fiber
June 16, 2026 Chicopee fiber has been a god send. The people who came in to install the fiber were very professional. My only complaint was that it took two weeks to get an appointment. The service itself if very reliable. We have yet to have an outage but our connection speeds and coverage areas have been very consistent. Lastly the price point is spot on and I like not having to have cable as we don't use that.

May 17, 2026 As a busy mom juggling freelance work and keeping up with two energetic kids, reliable internet is non-negotiable in our Boston home. We've been with Verizon Fios for years, and honestly, it's been a lifesaver. The speed is consistently fantastic, which means smooth video calls for my editing work and no buffering when the kids are streaming their favorite shows. Plus, with some of the "insider tips" I've picked up over time, I feel like we're getting incredible value for the robust service we receive. It just makes life so much easier when you don't have to worry about your internet connection dropping out.
