Customer Reviews for Internet Service Providers in California
Customer Reviews
Nick L.
Spectrum Cable
December 22, 2025 Spectrum is a moderately solid ISP. They occasionally have short outages that last a minute. This occurs maybe once every few days. For the most part, the speed is as advertised with good connection. The pricing is fair, however, this is after I had to negotiate with their customer service. If you don't regularly negotiate price with them, then pricing can be quite high. Their customer service is friendly and helpful, but they do upsell quite heavily. Overall, decent service at a decent price.
