I bought similar item from another supplier for twice the price and less features. The outer ring on the old device didnt have a motor. Also the outer shell was made of a flexible and infirm film which broke quite easily rendering the whole lamp useless. This device is much better - a stronger outer shell and rotates too It also produces music but I had to open the box and cut the wires going to the speaker because unlikely your child will like the high pitched sound. All in all projector works well especially when its close to the wall ceiling. And good price too
