Product review (4 stars): Make sure your heat and cool spade leads are connected in the correct order....
Board arrived faster than they estimated, kudos. I bought the board because my furnace was exhibiting short cycling behavior, even when the thermostat wasn't requesting a cycle. Only been a little more than a week since installation, but so far the problem seems to be resolved. Only reason I knocked a star off was that original board actually had the spade terminals labeled (heat, cool, park etc) and this replacement did not have them labeled with wording, only coding. Nor did it have the schematic of those leads included. It did list the leads in a way that made me suspicious that they were in a different order. Some googling later I was able to find a manual that showed that the heat and cool were indeed reverse order between the two boards.  I don't know that attaching those wires in reverse order would cause an issue for sure, but with no clear way to tell without googling for diagrams I dropped a star.  Other than that, happy with the price, delivery and (knock on wood) quality.
