Have used this shredder for several months. Destroyed about two baskets of paper in one sitting, without overheating, never putting more than two sheets in at a time, letting each group of paper complete it's shred. This is the third shredder I've owned and it is well worth the extra money. Avoid the ones on sale - just remember, you get what you pay for. Take care of it, don't overload it and it will last a long time.
