Product review (1 stars): DO NOT USE THIS!
This item was recommended to go with the Vicks humidifier that I purchased.  Since it was recommended by Amazon to go with the humidifier, I figured it was safe.  After following the directions and using a cap full per gallon, we ran the humidifier in our daughters room and it smelled like chemicals.  We immediately stopped using it and noticed the fine print on the bottle that says only for evaporative humidifiers.  I am pretty sure the humidifier being used is a vaporizer type so I am extremely upset that this item was recommended to go with the humidifier even though they are NOT suppose to go together.  Amazon needs to do a better job at marketing and advertising items that are in fact compatible!
