Looks interesting...for our smaller biz clients that we don't get on UTMs...
I ahve just set one up for in house testing.
Unit is metal cased with the usual Unifi glow on it.
Adding to my cloud controller took some time but provisioned OK evntually, most likely due to my broadband setup. You need the WAN connected for it to be seen in the cloud based controller. (obvious now)
Some interesting features:
Deep packet inspection (in beta so not on my default) seems to work well
You can enable it to run a periodic speedtest (in beta)
Port wise it has a console, WAN, LAN & VoIP
You can enable the VoIP port to be a WAN2 in failover mode in testing this was really quick BUT it will not move back to WAN1 automatically (as far as I can tell) My WAN1 is Virgin Media (home) so DHCP, WAN2 is FTTC so PPOE
I have yet to play with the Site to Site VPN
Some things need a Unifi Switch to function but it tells you which such as DHCP Guarding and IGMP Snooping
Over all first impressions seem good, integrates well and plays well with my on UAP
