I just got this for my enclosed back porch.  It’s PERFECT!  It’s small and the pump is quiet.  I was a little concerned when I got it out of the packaging because there were some internal broken pieces but I shook them out.  The outside of the fountain was in damaged. . The water and lights were entrancing to our 2 1/2 year old grandchildren.   The generic directions  were ok but not great. It really never gives you an exact amount of water to put in.  Based on another review I used distilled water and kept checking until the submersible pump was covered. 

Actually I couldn’t hear the pump just the soothing water.  I may get one for our bedroom!
