Negative Positive
Title: Fun but expensive to keep running.
Review: The aquarium is great to look at and listen too, but I have found that I am constantly having to replace the batteries. My daughter isn't even in her crib that often and yet the few times I use the aquarium, I am always replacing the batteries. It seems like so many baby items require batteries now, what happened to wind up items? It is lots of fun, but I find it somewhat inconvenient to keep it in working order. They should have had a wind up version maybe with a solar powered light.
Is the review positive or negative?
