I agree with Roger Slapes review, except for the star rating! My P70CM has worked for 3 years, but never to the performance claimed by Fellowes. It has competently shredded 3 or 4 sheets of 70 gsm, but it got really unhappy when asked to shred credit cards or an envelope folded in 2. It makes a bit too much noise. Finally, it decided to give up when my wife gave it an envelope. Lots of reversing and forwarding finally cleared it, only to find that it had shredded all the teeth off one of its cog wheels. I'm off to buy a different sort.
