My little girl has had this since she was only a couple of weeks old and still uses it now at 14 months. It helps her drift off easily to sleep and even if it doesn't do that, it keeps her entertained so that I can get a bit of peace and quiet. It has a choice of three sound settings- nature sounds, lullabies or a mixture of the two and they are all really calming and relaxing for baby. There are also switches to control volume, how long it stays on for and also one to focus the light show that is projected onto the ceiling for baby to look at.
Even if baby doesn't like to watch the light show on the ceiling, the screen on the front of the toy shows the little bear rocking gently on the moon and the starts slowly spin around him and light up which is lovely. Also on the front is a large button for baby to press if it stops and he or she wants it back on, and it is sound activated too, so when baby wakes up and cries it starts playing again.
The only problem is that the batteries run out quite quickly and it takes four of the large C 1.5v batteries which aren't the cheapest. However, I really don't mind buying new ones every week or two because my daughter loves the toy and I really see (and hear) a difference when it is out of power because she just will not settle without it.
This reasonably priced item is definitely worth it and great value for money. I really can't fault it for keeping baby happy.
