I love this waterfall and it’s gentle sound that would flow through out the room, easy to use.  Until, I left It empty for 8 weeks than came home and filled it only to have it leak in the seams of the base and sides.  Bummer!  I am going to try some gorilla waterproof spray inside to see if that works, yep I like it that much.  Sure wish this wouldn’t have happened in less than a years time.
