Review on 🔌 Arduino UNO R3 Compatible ARCELI ESP-12E ESP8266 UART WiFi Wireless Shield by Richard Deng

The board LOOKS good, nicely designed and well made. BUT there was no documentation at all. There are jumpers, dip switches, and connector pins on the board and it's impossible to know what they do. Made three attempts to get information from seller via email. All three received useless replies. The first two received reply emails with attachments, which were tiny PNG files showing the body of the email itself. The third answer contained an attached PNG file, which in turn contained the URL of a semi-Chinese blog describing ANOTHER BOARD. The seller doesn't seem to know what he's selling and doesn't seem to know much about using email or the internet.
