By chance, I saw this learning machine. It happened that the three-year-old boy was learning letters. After reading the introduction, he felt that he was very fond of me. He paid a deposit on the first sale. After waiting for a while, he received the goods. The quality and appearance of the rice elephant products were very reassuring, simple and practical, and felt good. His pronunciation was very clear, the sound quality was good, and the feel of the building blocks was also good. We will continue to review it later.
