Got this attachment for Christmas and I love it!  It takes a little getting used to using the scale for measuring (which you don't have to do, but I like that idea behind it).  And it sifts the ingredients into the bowl slower that I would be doing manually, which keeps the "puff" to a minimum.  

I've also used the scale to weigh things outside of baking.  I love the variety of what I can do with this! [This review was collected as part of a promotion.]
