According to Kitchenaid, this grater is suitable for hard cheeses, carrots, cucumbers, etc. However, when grating these products, the grater fills up and you always have to switch off the machine to pick the grated product from the grater. What does fall out of grated product, is thrown in all directions by the grater. Even if you have a high, wide collection container underneath, a large part will still end up next to the container. In addition, smaller pieces that you throw in the filling opening end up between the grater and the housing, causing the grater to become stiff or jam. I have tried grating different products but none of them gave a good result.
