Since this is a PoE-powered switch -- if you have a "core" switch that provides PoE, you can power this little US-8 via PoE via the core and without a wall adapter. Why would you want this feature? I have my core switch on a large UPS that can power it for hours. By using PoE-powered edge switches, those edge switches stay powered in a power failure without having to put a UPS at each one. Also, I have some places where I don't have wall power handy. That said, the US-8 comes with a regular wall transformer that can power the switch instead of input PoE. I did some testing and the US-8 unfortunately will NOT hot-swap between PoE power and wall power. So if your US-8 first powered up with the wall adapter but also has PoE input power, and you unplug the wall adapter, the switch has to reset itself (and drop connectivity) to transition to using the PoE input power.
This US-8 also has a pass-thru PoE (output) port on #8. Port 8 has PoE output turned OFF by default.
So, to summarize the PoE situation, this switch can accept PoE INPUT on Port #1 to power the US-8 and can be configured to OUTPUT PoE on port #8. I found this very useful where I had only one ethernet drop to an area for a PoE cam and wanted to add a Smart TV via ethernet without losing the PoE cam.
All 8 ports are gigabit and I get expected throughput via the US-8.
I'm very pleased and have deployed a bunch of these in my home/home-office.
So, when I needed a POE switch with a small form-factor for the lake house we had just purchased, it was a no-brainer. Or so I thought.
The first switch made an obvious exit within six months (completely dead). The second switch chose a less revealing failure by pretending to be functional (lights were on) but would not switch traffic (nobody home). It only lasted about two months.
When I received notifications that the various smart-home hubs/devices were offline and was unable to access anything remotely, I had my suspicions and ordered another switch; this time a managed TP-Link for about $40 less. This latest switch runs significantly cooler than the UniFi switch. Surprisingly cooler. The point I'm trying to make is that the UniFi switch ran hot. Way too hot, based on my experiences as a data-comm engineer..
For the record, the equipment is in an environmentally controlled room (temperature and humidity) with surge protected, pure sign-wave battery backups providing conditioned power for everything. Other equipment sharing this space includes a router, Access Point, various smart-home hubs/controllers, and a Synology NAS, all of which have performed flawlessly.
I hope this helps. I wasted over $220 on what ended up being a 100% unreliable device, twice. This experience has not sullied my opinion of Ubiquiti, only a segment of their product line. Time will tell if the $75 TP-Link proves to be a winner. We'll see.

I purchased the switch to work alongside a pfSense router which it is performing flawlessly till date.
Setup was very straightforward with unifi controller.
With the help of online tutorials, I have also managed to configure VLANs and trunks which is bit tricky the first time.
Device itself is very compact which can be fixed to a wall. In terms of device temperature, still early days, but running at optimal temperature so far.
i found installing unifi controller on raspberry pi much cheaper than going for unifi alternative.
Straight out of the box, devices supports 8 Gigabit connections with 4 POE. Point to note is that it only supports the IEEE 802.3af standard (48 volts) and doesn't cater for the 24 volt passive devices (although the 150W version does). An adaptor is available for that from Ubiquiti (INS-3AF-I-G Indoor Gigabit Adapter)
It warns you to have airspace around the device and it does run warm to the touch! Straight plug and play, out with my unmanaged switch and in with this which reports back on port usage and speeds to the ubiquiti Unifi controller. Lights are on the top so no bending down to see what the port speed or PoE status is. It also checks for firmware updates from the web and informs you through the unified controller.
The unit was supplied by NetXL and their service was so fast - the next day on all purchases I've made.
Bear in mind this switch is NOT passive 24V PoE compatible - if you want to drive something that needs this (eg older UniFi AP or CCTV cameras) you'll need an in-line adapter. Ubiquiti Networks INS-8023AF-I Instant Power Adapter or the Gigabit version Ubiquiti INS-3AF-I-G Indoor Gigabit Adapter .
