I like the concept, but I didn’t realize that the entire posters would be so thin and flimsy. You have to put in against a hard surface (like hang it on a wall or on a hard floor) in order to be able to push the buttons. And it bends easily. My kids like hearing the zhuyin words, but I don’t feel like it’s going to last very long. Also you can’t push the raised zhuyin letters, only the little circle in the bottom corner of each letter
