I have it and I love it! No more dry ingredients at the bottome of the bowl and no more stopping to scrape the sides of the bowl. it was worth every penny.
I have it and while I will use it, it is not my favorite blade to use. It doesn't fit in my mixer just right so that means anytime I am going to use it I have to adjust my mixer to fit it so that my mixer can lock and then re adjust the mixer when I want to use a different blade. I also found that it didn't work exceptionally well in my bowl but that could be because it was not 100% adjusted correctly. Hard to say. I received a different blade for my larger kitchen aid for Christmas but have not had the chance to use it yet. I believe the name of that blade is beater blade.
