I've used 2 or 3 of these now and they work as expected, I've had no problems. I had to make a multiple plug and socket breadboard compatible adapter for them, but I expected that and it wasn't that hard. I program them using a CH340 serial adapter on which I soldered a jumper between GPIO0 (pin 5) and GND (pin 1) and a push button between Reset (pin 6) and GND. In general they work as expected and I am satisfied. I'll probably buy more later.
