Really useful.  Makes good bread dough and sliced 10 lbs of sweet potatoes  in about 7 minutes.  Be very careful of the SHARP blades.  I cut into my finger and it bled all that day and took 2 weeks for the cut to heal.  I deeply suggest buying the storage case right away for the blades and slicing disks so this does not happen to you.  Shredded carrots very quickly and I dehydrated about 15 Lbs of carrots with very little work.
