We bought this for my daughter loves music, and we thought was nice that she might walk around with his favorite music from home. We already had a musical night of the Playskool brand and needed something simple to handle like that. We were also attracted by the ad, saying it was "a real MP3 for children," but in fact this is not quite right, as a real MP3 lithium battery has a long life and easy to recharge. We knew he had the LR14 batteries, but we thought they would term a few months, it is the case of my daughter pilot lights most of the day. While not all batteries have held twenty days! it is a toy that is too expensive and not environmentally friendly at all!
