Out of curiously, and this is a real question, how did netonix pick of the market share they did while offering utter garbage? It's not even like they're garbage ubnt cheap, that I understand, I poke the 3 am Ubnt fat girl at the end of the bar regularly, cause she's cheap and fat so not going to be a problem. But netonix is like 90 percent problem from what I read. You never hear about a high maintenance fat chic because there's no interest. How's this tubby broad even in the discussion?
