Review title: In search of flat bottom dadoes...
Product review: Regardless of the precision of the blades/chippers, you are still at the mercy of the arbor threads (the threaded portion of the arbor can be a lesser diameter than the nonthreaded portion allowing most of the blades to be off center). A blade or chipper that is not perfectly centered on the arbor will cut a little deeper than a centered blade (think about it). You will notice a vibration increase as well. In my limited woodworking experience, I have seen some arbors with flat top threads...anyway, I would not blame the blades until I measured all diameters and had some data behind me. 5 stars until I have a Freud dado set to complain about.
