What 18 Arbolus experts think of Gamma Communications

NPS scores trend in the 7–10 range for most experts, with a cluster of promoters (8–10) offset by a few detractors (5–6).

Most implementations are mature, with 75% active for more than 1 year, signifying solid stickiness. Key themes include praise for reliability and integration, but also concerns about lack of advanced features and inflexible pricing. Overall Customer Sentiment: Neutral to Positive
