Worth it!
I read all the reviews before I purchased this...did my due diligence since I desperately need to use a humidifier and essential oils at night for my dry eyes and nose.  I love it.  It works beautifully both with or without essential oils.  Easy to clean.  My husband never wanted to deal with our former humidifiers, now he doesn't mind dealing with this one and reminds me to turn it on nightly.
