Well, it doesn't exactly dice. You have to first do a matchstick cut and then put them back through for the dice. I might use it for the matchstick, but then I'd just use a knive to finish the dice rather than resetting the blades. I didn't consider the matchstick fries what I call matchstick fries. Whe I think of matchstick, I'm thinking McDonald's. These were much thicker, but maybe the thickness setting would give me what I want. Looks like even julienne is a two step process.
The other thing that bothers me is the size of the chute limits the size fruit or veggie. We get some pretty big onions around here that wouldn't fit in that little chute.
