(This review was collected as part of a promotion.) I got this for my Professional  6-Quart Bowl-Lift  mixer about a year ago.  It helps With creaming butter while it scrapes the sides of the bowl. It gets all way to the bottom of the bowl and up to the top,it helps a lot with smaller batches  that seems to be when I have to scrape the sides more. It saves some much time not having to stop the mixer and scrape the sides of the bowl all the time. this is such a great  product.
