Query: Leaked

I ordered this for my son's room. I used it once, and it worked fine. I didn't think anything of not emptying it b/c he would use it again that night. However, when I went to his room that evening, the humidifier had leaked all over his dresser and onto the floor. I tested it again later in the bathtub. I made sure I had it closed tightly and it wasn't leaking when I put the container on it. However, it leaked again all over the tub. I was very disappointed and plan to return it.
