I have looked at Airband before and whilst I haven't used them and I can't anyways, they seem to be a pretty good company looking at everything they have been doing so far. They currently serve Wireless Broadband and FTTP (Fibre To The Premises) and can do I think max 50 down on Wireless on Gigabit down on FTTP. I think they are a good provider but your decision to move over there depends on who your currently with and what you are currently getting at the moment.
You know when something isn't known to work well but it actually works for you quite well? It's a common occurrence for me. Just need to reach for that fibre cable.
