Query: Faulty

Unit failed within 2 weeks. Unit keeps running when no pencil is inserted. Tried my best to get it working again but problem continued. Also, when it was working, the unit would spin on table unless you held it down. Underpowered and not worth the money at any price. So frustrating I tossed it in the trash instead of returning it! Stay away from this brand... I bought another unit from Office Depot -- not an X-Acto of course, and it works GREAT! Suggest others do the same and avoid the X-Acto pencil sharpeners.
