I bought this for my special needs son. As other reviewers said, the demo was fine. But once put on ON, the noises were terrible, I am not sure what they were, but sounded disgusting and oh, so loud. I have to say that my son loves noisy toys and noisy books, but he did not want this one. Everytime he was presented with it, he would throw it and shake his head. And believe me, he loves noisy toys.
So, I am not sure if this would suitable for a young child.
If you leave on the OFF button, it is quite a funny toy, but it would make it an expensive one.
If someone is interested in this toy, I think it would better to try it first in a shop and not just on the Demo button.
