Product review (1 stars): Garbage. The hydrometer never functioned properly
Garbage.

The hydrometer never functioned properly, so even though the room humidity was 25% over where I had the unit set it stayed on.  The water it spews soaked into a rug and caused mildew.  The tank didn't even last a day when it did function.  This is a piece of s-hit product.  AVOID.
