It's a cute little fountain and definitely needs full sunlight; otherwise, it puts out intermittent water spurts according to how much light it receives. I put it in the small pond of my water feature, and it works fairly well; however, the suction cups don't always stay attached to the glass base I set beneath the water.
I bought this back in December and 1 1/2 months it still has not worked at all. I left it all this time on my pond with enough water to produce the stream under the daylight and nothing. Very disappointing. Only good thing it was that I got a full refund and the process was super simple. Definitely not worth buying.
