Query: Terrible!

This product was advertised as having a metal grater. However, when I received the product, I found that the grater was actually made of plastic, which made grinding very difficult and even more trouble than it was worth. At times, I felt as though I was using my entire body weight to grind simple foods, such as rice and noodles - even after blending them in my food processor first! In the end, I sent it back. I would highly recommend all interested to avoid this product entirely!
