Query: Disappointed by Penguin humidifier

My husband and I purchased the penguin humidifier several months ago after moving to Scottsdale. We initially used the humidifier without any problems. Then, we put the penguin away for the summer. When we took it out again last night, it wouldn't work at all. We checked the user's manual, and it appears that we are doing everything correctly. I guess we're out of luck! I should have trusted the large number of negative reviews and chosen a more reliable product. While the humidifier is really cute, I wouldn't recommend it based on its sketchy reliability. It was a waste of money.
