I always advise ppl against ubiquiti devices.
They are not open at all, its yet another proprietary router/switch/wifi/nas/etc
So what ? It's not possible to be reliable, open and have many features.
It's like being apple-everything. Freedom until you bump into the walls of your cell.
Unifi APs are a sweet spot of price/performance, and I have no difficulty recommending them. Ruckus hardware is better at five times the price.
UISP gear has worked very very well for me for ptp and ptmp. But that's a completely different line.
