That pay extra for more bandwidth just kills me. And that cost, with limitations, just is not attractive enough to justify switching unless they could show something on paper that gave compelling reasons why it would be worth a look. Something like higher sustained throughput where maybe the other peaks high but only has half the sustained throughput, or it can reliably handle 20 seperate camera streams versus ony 10 of the other brand, or something like that.
As far as tech support goes, after being long time users of Ubiquiti, we've finally gotten tired of what seems to be downward quality control issues over the past couple years and limited support options and am now using Deliberant, which has phone support and is about that same price. We just started using them, so don't know how they will work out long term, but the point is we did not immediately go for a $500 product as a replacement.
