Clean little product, two metal stampings and two bolts with plastic knobs which secure the stampings to the side of the saw table.  Very easy to lay the molding to be worked against the fence, top side on the table and bottom against the fence with the mounting surfaces flat against the fence and table.  This accomplishes what the Kreg Crown-Pro does and has the advantage of being easily able to use, for instance, the workpiece supports on the DeWalt miter saw stand, DWX723 or DWX724.  One thing of importance is to set both stops to the exact same distance.  Having set one to the desired position and secured the retaining bolt, use a straight edge to set the other stop.  An alternate solution is to determine the desired projection and cut a strip of wood to that width and then put that strip on the table and against the fence, then bring the stops up and secure them.  The straight edge method is much easier.  With crown stops, no tricky compound miter cuts are necessary, just make the miter adjustment and cut the molding.  I would highly suggest getting a good angle gauge, which should pop up in the suggestions if you are looking at the DW7084 Amazon page.
