I found the ubiguiti unifi gear some time ago when I was trying to find a solution for spotty wifi in my house. I tried lots of consumer grade stuff and it just didnt work. One unifi AP and my wifi has been stable since. Ive now expanded my unifi network to include the 150W switch and USG. Setup was easy and having the POE for my AP and future cameras is nice. One complaint is that the unit gets warm to touch and reports high CPU temperatures which I believe is normal. Having the unit mounted on its side reduces this temperature by over 10 degrees C.
Product is working fantastically in conjunction with two nano-hd access points and two non-poe 8 port unifi switches. Powers them with no issues. The sfp ports host two ubiquiti rj-45 adapters nicely, but it's important to note that these will ONLY operate at 1000Mb - you can't connect 100Mb gear to them (it just won't work). Fanless, which is why I bought this over the 16 port switch (it lives in a bedroom).
