Review on Raspberry Pi Ethernet/USB HUB HAT Expansion Board with 1 RJ45 10/100M Ethernet Port, 3 USB Ports Compatible with USB2.0/1.1 - Compatible with Raspberry Pi 4 B/3 B+/3 B/2 B/Zero/Zero W/Zero WH by Alejandro Labustin

Ready for immediate use. The Ethernet and USB ports are working properly. I didn't use the included stands as the 40 pin connector and micro USB to micro USB adapter keep everything secure on the Pi. Enough room for a small heatsink on the Pi. The indicator lights are a nice bonus. There are two downsides: 1) The Pi runs 1-2 seconds warmer. 2) The Pi will likely draw more current. I have not checked how much more. None of these shortcomings are a problem for me.
