I really like this fountain. I've been using it since April and it works well. Bear in mind, it only flows while the sun is directly on the sensor, so if a cloud rolls by, it will shut off. I happen to like that feature though. I set it in my garden on a tree stump and it really looks great. On our fountain, the pump functions better when the frog is not sitting directly over the hole. That's the only reason I didn't give it 5 stars.
