Query: I've seen greater.

This grater is not the greatest.The pyramid shape looks cool and everything, but the closed top design and the way it tapers off on the inside make it very challenging and annoying to clean.The best part about it is I didnt buy it. It came with my apartment. No one likes it. I just saw it while shopping for a new one and thought I would take a second to warn the people.
