I own this model, and use it to humidify a small room. I sympathize with the author's complaints with respect to the difficulty of cleaning it, though mine just doesn't need cleaning very often. And the wick DOES get moldy if you let it sit in wet water for weeks on end.

But her other complaints puzzle me:

I don't find it to be messy to refill. What is she doing wrong?

It's even more baffling that she thinks it "doesn't work". I mean, she refills the tank every night, so we know the water is disappearing from the tank... where does she think the water is going? Isn't that proof enough that it does, in fact work?
