I bought this food processor attachment for my KitchenAid food processor and it fits it well and pops right on!  What I really like about it too is that instead of having to buy 3 or 4 different attachments and it taking up room, this one does it all in 1!  And not only that, but it takes up less space and it's so handy to have around!  It takes care of everything and I'm enjoying using it!
