Review (5/5): Glad I purchased this!
When I purchased this, it actually was not what I was looking for at the time. I searched humidifiers and came across this and decided to buy it thinking it was a humidifier that could also do aromatherapy.
I live in Colorado where the air is extremely dry and to get real benefit from a humidifier you need a much more hefty machine that cranks out much more moisture than this item does; so I don't recommend this item if that is solely what you are looking for. However, the benefit this product offers from aromatherapy may help with some of the reasons you are looking for a humidifier. We wanted a humidifier because the dry air leaves us with dry skin and frequent sinus and respiratory infections.
I read the little booklet that came with the product and saw that eucalyptus is supposed to be beneficial for a decongestant and helping with respiatory problems. I happened to have some eucalyptus on hand so we decided to give it a try and it was the first night in several that my husband did not wake up coughing every couple of hours.
So we now have both this and a more powerful humidifier set up in our bedroom and we are very happy with them. We are actually both considering buying additional units for our offices!
We also love the soft glow of the light at night, we find it to be soothing. If that is not something you like you are able to turn the light off by pushing the button several times, cycling through the color options.
