It doesn't matter. I bought a panda English trainer for my sister's children on Children's Day this year. She was 6 years old and loved it when she received it. According to my sister, every day after coming home from kindergarten, the little guy will learn English with the morning education machine. In less than a month, he can read a lot of words. I took a fancy to it when I bought it, because it is an American brand, focusing on English enlightenment, from a personal point of view.
