I bought Ativa 8 sheet shredder at Office Depot. I only shredded paper although it claims it can shred credit cards. After a month of home office use, it jammed. When I flipped it over I saw that the plastic feeders and metal wheels in the roller assembly were bent. Bent from shredding less than 8 pages of standard office paper!

It has since gotten worse and now I can use it at all. What a piece of garbage!
