I have been with TPG for 20years and haven't had any issues for a long time. (used to know when they were advertising a good deal becasue speed would die for a couple of months). Speed has been reliable for years and no CGNAT to worry about. Support is off shore but rarely have to call them.
I was about to churn to Carbon Comms last month who were advertising $80 100/20, with static IP, on OZBargain. But when I called TPG they beat that to keep me loyal.
