I use this with my QNap switch with 2.5GbE ports and my M1 MacBook Pro running macOS Big Sur. Although some applications that test network connectivity report that it only works at 1 gigabit, I can confirm Pluggable's words that they do indeed work at 2.5 gigabits. For the price, functionality can't be beat. I would buy it again, except my new NAS has a 10GbE connection, so I'm upgrading to 10GbE (SFP+) and Pluggable doesn't have either (yet?). So I get a QNap model.
