I would rather listen to my mother in law than listen to the noise this machine makes. It jams easily and is a mess to fix when it does jam. I would suggest other name brand units. Probably a little more expensive but worth it.
The shredder gets stuck sometimes and I had to get a replacement. The staples team was fast and efficient in sending new machine! Would recommend staples any day.
We employ adults with special needs. We had a need to keep them busy during slow production times. We used to buy one commercial shredder but our crew just shreds a few pages at a time. Decided to buy multiple smaller shredders so everyone could shred. This one overheats if you use it consistently. Also purchased basically the same shredder from other companies and have not seen an overheating problem on them.
