I only had the chance to use this item once, when I received. I bought it ahead of time for a child and when I finally got around to using it, it never worked. I have another friend who bought the penguin and had the same problem. It only worked the same day she bought it. Luckily she was able to take it to a store where she had to exchange 3 times before she gave up. You don't even have the benefit of exchanging on this product. Save your money and don't go with the cutesy humidifier, you are better off just getting one that actually works.
