Query: Royal should have shredded this sucker before it was marketed!

The safty on/off mechanism fell off a week after we got it. The "Auto" feature, always on and cuts when paper is inserted, stopped working a week after we got it. It chokes on anything more than three pieces of paper. It's a piece of very poor quality engineering. I would stay away from all Royal shredder products after this experience!
