So far, no real complaints. As one consumer did mention the noise volume on med-high is very exceptional. Depending on your perspective--it's great for drowning out noise should one like to be in a really deep sleep.

This humidifier is GREAT! I had previously bought another brand, but was not happy with it at all. It claimed to last up to 12 hours when really it only lasted about 4. This lasts all night! I can use this for a few nights in a row before having to refill! Love it.
