It does what it is supposed to do, It keeps the motor cooler. That said, it could be better. Vertical fins would allow flow all the way around. The horizontal fins allow easy flow only around the front facing fins. I added some simple duct work to force feed air to the back fins. It would better if some heat conductive compound was included. Finally, the fins are a little too long to fit next to the mounting bracket and WAY too long to fit next to the mounting bolts and nuts.
