I have had a shredder about 10 years that works great, but would only shred two or three pages at a time. It was time consuming if I had a lot of papers so I decided to purchase a new shredder. This one is supposed to handle 12 pages of 20 lb. paper. It worked great on a few pages, but when I tried 12 pages it jammed. I have been trying to unjam the shredder all afternoon. I just received the shredder last night and this was only the second time that I used it. My other shredder also has a much larger opening for the paper. The paper has to be perfectly straight across the bottom before you can feed it into this shredder. Right now I'm not happy, but time will tell.
