I have owned this dado set for 8 or 9 years.  It has never cut very well, leaving rough bottoms with a lot of chip out.  It got to the point that I used my router or router table for most dado operations, avoiding the Freud dado set altogether.  I have owned other Freud blades for my table, miter, and skil saw.  These blades have done a good job at a reasonable price, but this dado set has been very disappointing.  I would not buy recommend it.
