My daughter was having trouble with memorizing her multiplication equations. I used this very item when I was a child and it worked wonders. When I found it I was so thrilled to get it for her. She uses it everynight to help enhance her math skills. Very durable product, it has been dropped several times and is still in perfect condition. Item is fairly big to take to school, but we have a special bag that we carry it in. It is easy to read. On the tops of each button is the actual equation and then you simple press down to read the answer. Great product!
