Query: I'd rather scrape my knuckles on a regular grater!

I received this as a Christmas gift. I had high hopes for it because I love using grated cheese and this seemed like a great idea for a product. I charged it and then put a small piece of cheddar on it. If you push on the cheese at all it stops the machine. But if you don't push on it, it doesn't really grate the cheese. It made a few cheese crumbs but that's about it. On the plus side it is very easy to change grater attachments and it comes with a wall hook for storage. I never did install the hook though so I don't know how well it works.I didn't save the box so I can't return this and I can't bring myself to give it to someone else when I know it doesn't work. So this one is a complete waste!
