Just bought this and it arrived in time to use for Thanksgiving. I used the fine shredding blade for crumbing cornbread for dressing and the dicing blade for my celery and onions. 
I usually use a blender to crumb my bread and have to blend small amounts and dump, but with this attachment, I was crumbing the bread as fast as I could get it in the feed tube. It seriously took longer to wash the veggies than it did to dice them. I the dicing blade was perfect for this use, but I think I might like to have a dicing blade that would make larger pieces for other uses. Can't wait to try the other disks after Thanksgiving. I would like it if the storage case would hold the entire attachment instead of only the blades. The dicing blade is a little hard to clean, but that happens with any dicing blade.
