If I were you, I would choose little genius. Little genius's machine is a little more expensive, but it is rich in content, especially the suit, which is still very comprehensive. Many interactive games, and their products are of excellent quality! I worked with cradle. It should be more professional! In fact, the point reading pen is not bad, but personally, compared with the little genius, its educational form will be relatively simple, feeling more like a player, unable to see the content and interaction.
