I am with DoDo for my NBN setup and installation was fantastic, on time and painless even got 2 months free. since i joined several months ago i have recieved efficient and courteous customer service from helpful team members, any problems were quickly identified and resolved. I have a fixed wireless service which runs at a maximum speed of 25/5 and the speed is constant, never dropping under 90% of promised speed. Any planned scheduled maintenance is always published on their website so you are pre warned of any dropouts in service.
