Query: Not a Shredder!

I should have read the reviews before buying. This device is not a shredder in any sense. It does not shred! It makes some pits on the data side to make it harder to read, but leaves the actual data layer fully intact! How can you call this device a shredder?!? A complete rip off, and offers virtually no security.
