This is an upgrade for me as another shredder I purchased TWICE in the past 5 years seemed to give up the ghost, mid shred, about two years in. I hope this one will be sturdier and last longer. From first impressions, this seems to be sturdier out of the box. I really like the casters and rolling ability. This was an easy assemply- open box, plug in, and shred. Hope it lasts!
