Excellent OpenWrt Router
Setup was straightforward. The dual NICs work perfectly for a firewall setup. Metal case keeps it cool.

Good but needs knowledge
Not plug and play for beginners. Had to flash the image myself. Works well once configured.

Great performance, slight heat
Runs Docker containers smoothly. The fan is a bit noisy under load but acceptable.
