It lasted about 5 minutes of forward shredding thick cardboard and about 10 to 12 sheets of paper and then would not run forwards anymore. It was only made for 5 sheets max. Then I could only run it in reverse but the paper jam would not come out. Then I took it apart and got all of the jammed paper out of it. I tried shredding in reverse again and then the engine sounded like it was not hitting the gears right. So I then took it out behind my giant zipline in the woods and chucked it over the fence. Then I went down my zipline and on half of my slides at my playground! No more 4.50 dollar shredder anymore!!
