We wanted a small pond in our backyard but didn't want to have to use electricity. I thought this solar fountain would be perfect, giving some circulation in the water, plus looking pretty. It did just that for a couple of weeks ONLY when in direct sunlight, but since then, has decided to quit working most days. I don't know if there is a short or what, but the fountain does not even come on most days now, even in direct sunlight. Unfortunately we threw away the box so I haven't tried to return/exchange it. I'm now looking for an alternative.
