Query: Not as great as you might think.

We registered for this and thought we were lucky to receive it. After putting it together (it is very large) and turning it on for a test run we were very disappointed. The mobile makes noise while turning (clicking) and was very distracting. The mobile also gets stuck and makes a grinding noise until it gets going again. Needless to say - we returned it.
