I received the cloud humidifier as a gift at my baby shower.  I live in North Dakota, and during the winter, the air can get very dry.  I fill up this humidifier each night, and it's enough to provide mist all night while my toddler sleeps.  The options to use it as a nightlight are nice too.  After using this for a couple years, I was carrying the full tank one day and I dropped it, which caused it to crack.  I e-mailed Pure Enrichment to ask if I could purchase a replacement part, and they were kind enough to send me an entire new unit in the mail.  Love this cloud humidifier!
