I have had two of these shredders and the second one was a replacement for the first one. The second one didn't make it two years and I use it for very light duty. I called the manufacturer and they offered no help or support whatsoever. The machine would not shut off after shredding something. I was told that you have to unplug the unit after each shredding, so the shut-off sensor doesn't burn out. This is totally useless to have to unplug the unit after each use, plus the manufacturer didn't seem to care at all.
