I have no experience with the solar fountains, but I do have several types of solar lights around my yard. The only one I have problem with is the light that is connected to the spitter on my garden pond. The spitter itself is not solar, just the globe light that's connected to. It leaks water into the battery compartment so I have to change the battery out to a dry one frequently and I'm sure it's going to rust out sooner rather than later. Not sure how this relates to solar fountains themselves, but just some input.
