We buy this music lamp for our baby and friends baby. It would be great if it would be with battery, but it's only with cable. You can choose the stars and the moon colour, but they are not so bright. There is some songs, one song I don't like, but others is quite nice. It's good that when it's playing the bear colour is changing also it's stops after few minutes, so you don't need wake up and turn it off. My little girl like to lay and watch at the colours when she's trying to sleep. For this price is quite good product!
