content: After getting tired of looking for batteries for our other sharpeners, I decided to look for a sharpener closer to what I used in school. Well this one is not it. After three uses, the entire collection cup just came off and would not go back on after adjusting every way imaginable. In order to sharpen a pencil, the cup must be on securely and ours was just flat out broken. Also the pad on the bottom of the unit was very loose upon opening but we were still able to make it suction to our granite. Don't waste your money on this cheap plastic.
