Query: Big disappointment.

This mobile came highly recommended and we were so happy with it for 7 weeks. Then the mobile stopped spinning. I called Tiny Love and was told by their customer service representative that my complaint was a common one and that they would send me a replacement piece. The replacement piece never arrived. This product quickly went from being my favorite baby gift to something I wouldn't recommend to anyone. It would be great if Tiny Love could solve the spinning problem because it's such a good idea and my son loved it while it lasted.
