On first unpacking I was impressed with the build quality of the product. It's not "just a grater" it's a multi-purpose product.
You have a box grater with standard-size large and small grating on opposite sides. Cleverly attached to the side is a plane grater which can be detached, ideal for testing and hard foods like parmesan or even nutmeg. 
Opposite is a sharp slicer which produces nice thin slices of things like onions or cucumber. 
Attached to the bottom is a small graduated container which has graduations up to 300ml or 1 1/4 cups, very handy. It also has a detachable lid which can be used to seal what you have been grated for storage.
The top handle is rubberised making it easy to grip and use.
My old metal grater has now been retired.
