I used to have an earlier version of this attachment that worked really well at shredding cheese and not nearly so well at slicing vegetables. That one fed at an angle from the side. I was hoping that this one with a top feed tube would work better, but I’m disappointed. The zucchini sliced nicely, but the mushrooms were more shredded than sliced. Broccoli stems were shredded until I turned the speed up a few notches.  I’ll keep this because it’s better than nothing when I’m trying to slice up vegetables for soup or veggie pizza, but the results will never be very pretty. It will be good for shredding cheese, so I suppose I like it for that. I just didn’t want to have yet another whole appliance in my kitchen cupboard.
