Eir Fibre is good and installation by KN Networks was good. However, customer service from Eir was terrible. I was not advised that my DSL connection would be cancelled a week before Fibre was installed. Left with no connection for working from home, as I live 100km from work I came home from work with work to complete for a deadline the following morning to discover no connection. I had to get back into my car and drive 100km back to the offfice to finish the work and book a hotel overnight. No understanding from customer service team of the implications of not informing me that this would happen. Or that I was our of pocket for expenses
