Query: Good luck for shopping!

I would rate ZERO star if I can. Received a defective shredder out of the box, the shredder is obviously been used as there are still some papers jammed on the blade although the seller, amit16, claims the shredder is "brand new"! HUH? If you want to waste $10 to buy a trash can and a big trash, go ahead! OR You can also pay $10 to ship the defective unit back to get your $4 refund if you are such bad luck like me. Good luck for shopping!
