Cuts great dados.  Perfectly flat.  My only beef, and the reason I give it 4 out of 5, is it says you need both cutting blades, 3 chippers, and two spacers to make a 3/4 inch cut.  That's not the case.  I had to add a .020 inch shim to it as well, in order to get closest to the 3/4 inch cut I wanted.
