Query: Piece of Junk

I've been happy with many other KitchenAid products, but this one is pure junk. The pasta roller attachment that KitchenAid also offers is great, but the width of it is so close to the size of this ravioli press, that the edges of the ravioli barely have enough dough to seal - and many of them pop open.It's worth noting that although this does in fact attach to a standing mixer, it does not use the mixer's motor. You have to manually turn the crank with your hand.I returned this piece of junk, and bought the VillaWare V5500 10-Square Ravioli Maker for $18. Save yourself some money and do the same.
