6.3/10verdict: good, not the best

The UniFi Flex Mini 2.5G is for people who run UniFi gear and want multi-gig speeds on a small five-port switch. It suits a home office or homelab that needs a few 2.5GbE devices linked and managed from the UniFi Network application. It is a poor fit for anyone who needs PoE output, more than five ports or fibre uplinks.
