Well made, easy and fun to assemble.

It is what it claims to be and works well so far. Fun and pretty easy to assembly, a suitable kit for relative beginners.

Note to people who might think they can get around the AC Transformer thing (not included, as it mentions somewhere). I could tell from the pictures that this board rectifies and filters the incoming AC before regulating it down, so I thought I would use a laptop power adapter to feed it DC instead. That would have worked if I was right about how this board works. The main rectifier does what I thought it did, but there is a second smaller rectifier that creates a negative voltage to drive the control circuitry. This board really does require AC (unless you want to complicate things...)
