I am pleased with this turn vegetable. It works very well for potatoes, zucchini, etc ... (Even carrots, or other vegetables of small diameter and a little hard, the camera quickly dispelled our doubts and our in-priori). We have for now used only as "spaghetti", there are two other grids / blades to be tested which should work just as well, I suppose.
This is a manual, there is nothing electric, and suddenly, one can always pass it under the tap when we finished.
Disadvantage: it is a little bulky (about 20cm x 30cm for storage).
Advantage: It is stable, sturdy, removable, washable, convenient to use and to clean.
