I bought a Champion Shredder at Wal*lMart and it jammed when I tried to unjam it I saw the metal shreddings were bent  I was careful with it as to what I put in it but thought maybe I did something wrong so I went out to Wal*Mart and purchased another one exactly like the first one ...not too long after it also jammed and it too bent .  Now this time I was extra careful...also on this one it wouldn't stay on as I shredded I had to manually hold on to shred.  I am completely disgusted with it... the model type is  CHAMPION WQ120D  I will never purchase another that is for sure.  I am going...
