Reliable for IoT
Deployed ten of these for sensor nodes. All connecting reliably to our local server via DHCP.

Good value
Solid build quality. Setup was easy using the Arduino library. One star off because the pinout diagram was slightly faded.

Better than W5100
Upgraded from the W5100 and noticed immediate stability improvements. Handles multiple sockets well.
