Title: Buy only if you live in a lake
Review: I have had many ultrasonic humidifiers and this was the worst. While it may be efficient, quiet and produce high levels of humidity in short periods of time, the fact that I could not use it on the floor made it extremely useless. The size of the mist droplets, even on the lowest setting, must be much greater than all the other ultrasonics I had because this one constantly wetted the floor. To have to limit its use to putting it on a shelf several feet off the floor, obviates the convenience and this unit will just join the recycling bin, as mine will.
