Query: Don't buy this

I bought my Essick H12 400 13 months ago (Jan 07). It would not turn on after assembly. They had to send me a new and 'improved' replacement 'float rod' which turns the fan off when water is too low. The replacement part did not work either---an obvious design error, the stick was too heavy for the small piece of styrofoam to float and turn the motor on. I had to reach under the fan and push the rod up after filling. After 13 months the motor started overheating and stopping. I could hold my hand 4" above the motor and feel the heat. Threw it out. My old Sears humidifier ran for over 10 years---this one barely one.
