My 6 year old is ecstatic about the scanner. Installation was easy with the directions and a screwdriver. Entire unit is made of wood composite. This is a good looking and solid unit. With proper care it should last long enough for our next child. It comes with dollars, coins, credit card and prefab common merchandise cartons. This makes my child's experience with unit more realistic. Once completely build the unit is firm with no give. On the checkers side the kids could type in any number (its basically like a mini calculator) and the scanner will scan the cartons and makes the beep sound. On the buyers side nothing shows except when they swipe the credit card it makes a sound. Our daughter loves this unit and I would recommend this unit.
