I got this for my son and it is the best humidifier yet.
I've tried a bunch of inexpensive ultrasonic, evaporation, and heating element based units but this one is the first that actually went ALL night.
It has a output volume knob that actually works: High is as thick as pea-soup fog and low is merely mouth breathing.
There is a built-in filter on the water supply so that may extend the life a bit but I don't know yet.
The light's aren't the super annoying injection laser diodes that I've seen on other models.
The vapor direction nozzle is nice because you can point the power and water alarm lights away from your bed.
