Just came across this thread. I've previously posted my terrible experience with OpenNet
Bottle line is they are terrible. If you want to schedule a date outside the limited ones they provided, they will charge you. Even one day outside the allocate date, they will charge you $220-$450! No nego on date to come.
Their supplied material is terrible. It'll distroy the look of your place - cheap crappy material sticking on your walls. I want to hide it so need to bring in my own contractor since Opennet refuse to install in false ceiling. But contactor can only make it other date and Opennet refuse to come if I don't pay them $220. WTF! Government paying Opennet to do a job and they still want to charge coz they refuse to shift the date. Calling customer support is like talking to a recording - always repeat the same thing "we will charge you if you want us to come outside allocated date for your area!". Opennet just after $$$
I gave up. Rather go for cable than to be bullied them Opennet
