I recently purchased the attachment and am very happy with it.  It works very well on harder veggies.  Only issue comes with soft core veggies like large seeded cucumbers.  The holders are inserted into the core area and that material is not strong enough, so for large cukes maybe not the best choice, but zucchini, potatoes and other veggies, works great.  Blades are good and sharp. [This review was collected as part of a promotion.]
