This unit started breaking teeth off inside pretty soon after I bought it. I used it very lightly not often at all and only up to 2 sheets of paper at a time. Now a year and a half after purchase it's dead because too many teeth have broken off from inside despite the fact that I babied it along and had to pull out the jams every few times I used it. Do NOT recommend!
Compact and works like a charm. Only issue I have with design is that it’s emits high pitch sound. My old shredder was loud but duller sound (slower shredding speed). This one is not as loud but the sound is much higher pitch.
