I have been with Tikona since 2011 and been generally very happy. I moved to them after my previous ISP charged me out for excessive usage. After searching online forums for an ISP with clear, up-front conditions I moved to Tikona.
Since then, all those limitations have been removed(now unlimited all-day everyday), the broadband speed has increased, and the price has gone DOWN. Also, friendly, competent staff every time I had issues to sort either via phone or email.
