The learning machine Bought online the day before yesterday, received it today. I have not bought it before, this is the first time to buy it for children to learn, just take it back, will not play, wait for the child to come back to grope, friends, have you bought a learning machine for your child or the like? Is it useful? Is it helpful for learning? Kids can also be controlled to play!
