Hard for beginners
Requires knowledge of flashing firmware. Not plug-and-play for non-techies. Good once set up though.

Good hardware, weak docs
The board works great but the wiki link was broken initially. Support fixed it fast. Hardware is solid.

Perfect for Home Automation
Integrated easily with my MQTT server. The relay clicks are audible but satisfying. Great value for the price.
