Overall happy with the purchase given the price per unit.

Packaging/appearance


Also worked great in my final project, because it enables you to install the esp8266 module itself without having to install it.

Competitiveness


But it was difficult, i used this thing: usb to serial esp8266 esp-01 adapter wireless esp8266 ch340 that i also bought on amazon.

Positive Review

Worked using skr e3 mini/bigtreetech tft-35 connected to an creality ender 3 pro 3d printer.

    One of the 1mb has a bad efuse [bricked on arrived].
