Review on Raspberry Pi Ethernet/USB HUB Expansion Board with RJ45 10/100M Ethernet Port (RTL8152B Chip) and Three USB Ports - Compatible with USB2.0/1.1 | For Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/Zero WH by Jon Ford

Raspberry Pi Zero is powerful, affordable and small. Built-in Wi-Fi is acceptable but not up to par for speed or range. If you use Zero for network activities like Pi-Hole to block ads or provide VPN services then this is a great addition. It gets everything it needs through the USB connector, so none of the GPIO pins are blocked. It can be installed with the included standoffs without a GPIO header. Ethernet offers a real data transfer rate of 100 Mbit/s. Ookla data transfer test below. Latency: 11.11 ms (jitter 3.55 ms) Download: 100.92 Mbps (data used: 172.5 MB) This is an elegant solution to add an Ethernet port to the Pi Zero and requires no additional dongles or Adapter. They include a special USB to USB adapter that is ideal for connecting the hat to the motherboard.
