My Golden Retriever loves flowing water, and drinks more when the water is flowing. I've tried other pet fountains with pumps that have easily burnt out because the water level indicator is hidden, but with this fountain you can see the water level at all times. I like that it's stainless steel and not plastic, which I don't think is good for our pets' health. The water flow is weak no matter which attachment you use to determine the fountain style, but it makes for ultra quiet operation. I have found that there is less splash compared to a static water bowl, which means my floor is kept more dry. The only real down side is that it's a bit fiddly to clean.
