I wanted to try running Pi-Hole on a Raspberry Pi 0. Due to the size of the Pi, it doesn't have a built-in network card, and neither do I need anything as vital as DNS to rely on a wireless connection. That's why I ordered this adapter. It's pretty rare to find Micro USB to Ethernet. (USB A or C for Ethernet is more common.) I plugged it in, booted the Raspberry OS and it was off and running. Easy installation - it was automatically detected. Reliable - It's been running for all my DNS/DHCP needs for a few months and I haven't had a second of downtime. Great product, great price.
