My only complaint is the user manual. I suppose it's fine for those who have had fountains before, but I have no working knowledge of how a water pump works and the instructions were really vague. Like it says to not fill water past the edge (well, duh), but it doesn't really say how much should be in the bottom pool on a regular basis once pump starts working. There's diagrams that kind of show arrows and things, but look like a child drew them and didn't really make any sense (there were drawings of 2 separate models, and I'm still not sure which one was for our fountain).
Other than that, I would still highly recommend this fountain for a nice addition to your space's ambience.
