This is a brilliant gadget that saves a heck of a lot of repetitive knife work, and produces superb results - and it doesn't break the bank, either.
Someone else commented that they did not get along with this device for julienning carrots. Well, I've been using one for carrots for over 10 years - yes, raw carrots. Obviously, these are the hardest vegetables you would ever want to push through, and softer veg are much easier, but carrots *will* go through. You will need to quarter the carrots first, so they fit into the aperture; then use the right angle of the quarter in the corner of the aperture, and apply force - quite a lot of force, yes, but not herculean amounts (I'm no Sly Stallone).
I came here to buy a new one, although the existing one is still going strong - it is sometimes handy to have two people processing carrots at the same time (e.g. Christmas). One tip - lightly dust the carrots with dill, then steam them for about 10 minutes, toss them in butter and serve. Delicious!
