As an experienced pie baker, I bought this new beater to ease the work on my arthritic hands, thinking it would be an improvement on the regular paddle attahment.  What a disappointment!  This thing does not "incorporate" the fat into the flour ... it gums it up almost instantly on "Stir" setting.  It just makes paste out of the flour-fat mixture before I've even added the liquid,  Had to toss 2 batches, and at 86, believe me, I am no novice.  Stick with the paddle attachment and save your money.
