My son loved the mobile we bought to match his bedding; however, it was not battery operated, so we had to keep winding it. We decided to buy him a battery operated mobile with sounds and lights...this is the THIRD calypso mobile we've bought/exchanged. All of them quit working after about 2 or 3 days. The lights dim, the mobile stops rotating, the remote doesn't work, and the aquarium makes a loud rattle. This was the WORST BABY item we've bought.
