Decent but basic
Functions correctly but the pin labeling could be clearer on the silkscreen for beginners.

Perfect for my firefighting bot
Works exactly as expected. Drives the small fan nicely to extinguish candles in competitions.

Good value
Does the job well. Gets a bit warm under continuous load but nothing concerning for hobby projects.
