Query: Nice looking but not functional

This is a really cute mobile. When it was working, my son loved it. He talked to it for at least 20 minutes at a time. However, it stopped working after a couple of weeks. (And yes, I changed the batteries--twice!) The music played, but the mobile wouldn't turn. Another problem is that it does not stay in place. The base is very heavy, and difficult to secure to the side of the crib. The base twists, causing the arm to fall to the side, which could potentially hurt a child. It is very cute, but I would not recommend it.
