Input:
Disappointed is the best word to describe my feelings toward this appliance attachment.  It does the job OK, but onions are not it's friend.  There is a gap between the blade and the side of the attachment which allows onion or other fibrous veggies to squeeze in and create large, uneven slices.  So it works, but just OK.
