Excellent value for money
Bought five of these for my students. All of them worked out of the box. MicroPython support is a huge plus.

Good board, slight learning curve
Hardware is solid. Took me a while to install the drivers on Windows 10 but once done, it works great.

Good but pins are tight
The board works well, but the header pins were a bit tight for my breadboard. Had to adjust them slightly.
