The driver is good for the price but the ratings in the specification are exaggerated. The rated output current is 3 A and absolute max for the chip is 4 A. The board layout is good, PCB sinks heat very well, but the hand-soldering of THT components is terrible. Filter c(r)aps are smaller than they were supposed to and of very poor quality. Replacing them is recommended for improved reliability. Thermal grease is the cheapest available and applied too generously - smeared all around the chip. Other than the sloppiness during assembly, it's a very good product.
