Good value board
Wi-Fi range is decent for the price. Documentation could be slightly better for absolute beginners, but plenty of online resources exist.

Perfect ESP32 clone
Fast shipping and well packaged. All pins are accessible and the voltage regulator handles 5V input without overheating.

Bluetooth works well
Connected to my phone easily for serial monitoring. Low power consumption modes work as expected in my sensor project.

Solid beginner board
Pin headers were not soldered which was fine for me, but note that if you want plug-and-play. Performance is excellent.
