Installation in 3 minutes. Driver upgrade from the realtek site, connection with a 5-meter cat6a cable to the 2.5 port of the fritzbox from Cosmote and the speed reached 1070 mbits. No significant difference in the internal network since all other devices are on a gigabit network.
Cheap and honest device for the use I want. If there were cheaper switches and network cards, I would go for a 10k network.
I give it a 5 due to price and trouble-free operation.
