I had heard wonderful things about the older version of this toy. We purchased the newer version and had a lot of difficulty getting it to work properly. It was so big that it constantly pushed down on our bumper pad, and we were not able to get the screw to line up to make it work. It was heavy and bulky. I love the idea of fish, aquarium sounds and soothing bubbles, so we got the Calypso Mobile instead, which has many of the same benefits with some additional ones. (see my review of the Calypso Mobile).
