Excellent price. Works perfectly. Documentation is limited.

Mine has worked well so far. My only complaint is that the pins don't match the other ESP-32 development board, and the diagrams in particular have me concerned about the Vin5V pin. As with Arduino boards, my other ESP32 board had a 5V pin connected directly to USB 5V. This design allowed me to use it to either power the board or power small loads. This meant I could safely work over USB or with a single power supply: plug it into USB and 5V would power devices, plug it into 5V and it would power my devices and USB. It's not so clear here if I can run a small current through this pin. So I keep it powered via a 5V PSU AND USB during development.

Pros
