Amazon.com.au:Customer reviews: UGREEN USB 3.0 Hub Ethernet Adapter 10/100/1000 Gigabit Network Converter with USB 3.0 Hub 3 Ports for Nintendo Switch, Windows Surface Pro, MacBook Air/Retina, iMac Pro, Chromebook, PC
I am using this for the nintendo switch. I've been impressed with UGREEN with other products in the past and this is no exception. Product feels premium and does as is it says in the description. One thing to note is that if the switch dock is plugged into power, the blue LED on the ethernet adapter will remain on regardless if the switch itself is on. I like to disconnect the adapter when not in use as I don't want the light on.
Works perfectly on the Nintendo Switch. Did not cause any issues with switch overheating (Ethernet adaptors have in the past caused the switch to stay warm even while sleeping, i believe this is now fixed via software updates). Significant improvements in connection speeds over wifi.
