I was a bit skeptical about the purchase due to the mixed reviews and problems reported by some reviewers with downloading. I had no trouble using the Arduino and setting the board to "ESP32 Developer Module". Flashes without having to hold down the button. Several sample sketches I tried worked fine, including the WiFi client/server. Overall I would recommend this to anyone looking for an ESP32 based board to experiment with.
