Good device and good support for the ESP8266

Not only is the ESP8266 wifi module tiny and efficient, but the support was rapid and good. Bbtech was very open to feedback on their documentation and did a great job of improving the diagrams and wording. I bought another two modules based on my experience, and would recommend it to others.
