From my experience, these cheapo Unifi switches from Flex series are bad.

They heavily drop frames under even moderate loads (well under 2gbit). If you turn on vlan tagging, they won't hanlde more than 0.1gbit.

They work well if you need to connect a bunch of slow iot devices. Don't dare connecting them to a desktop.

The Ultra series of utility switches is rock solid though.

We used the 1GbE version in an outdoor setting to easily connect multiple sensors in a port within a research project. Good reliability and being able to extend and "split" the ethernet connection without additional power supplies was very convenient.

We did not integrate them into a UniFi ecosystem, just used the PoE and dumb-switch functionality.

Ubiquiti copies in a lawyer for what reason now? Reviewing a bought product. That is absolutely BS behavior.

I guess I shouldn’t be surprised, but still fun to see that they’re apparently using an ESP32 as management processor (without antenna, probably just RMII directly to the switch ASIC)

Edit: there’s a RTL8201 10/100 PHY to the left of the switch asic, that connects the ESP to one of the switch ports.

For home use I have got a bunch of very cheap ($20 each?) 2.5gbit switches with 4x 2.5gbit and 2x10gbit SPF+ off aliexpress. I've ran fibre round my house and it works perfectly.

With the upcoming Realtek RTL8127 based products I would rather jump to 10G straight. Sadly there isn't much competition in that switch segment, I couldn't find reasonable products besides maybe Mikrotik CRS304-4XG-IN.

Can't find RAM and CPU specs for RTL8372N. Would be interesting to flash OpenWRT onto it.

Is there anything comparable in the TP-Link Omada ecosystem?
