Query: Terrible slicer

The instructions that come with the rotor slicer/shredder state that the number 4 slicer attachment can be used to slice cucumbers to pickle, so I tried that with one cucumber; not only were they sliced too thin to be pickled but they were also sliced unevenly and basically mutilated. So then I tried to use the number 6 "thick slicer" thinking that attachment would work, but it doesn't really slice any thicker and actually just caught the cucumber skin under the blade and mushed my cucumbers. I ended up not having enough food to properly pickle and wasted $20 worth of food. I have never been so disappointed in a Kitchenaid brand item before. Do not waste your money on this attachment if you want to slice things, you will simply end up having to slice your veggies yourself anyways.
