I was SO excited for this diffuser. I bought it a few months ago and I was so happy about the two chambers and the ability to have it automatically turn on right before my alarm clock. However, it is super underwhelming and I am really unsatisfied with the product. I really just don't think it diffuses very well. I talked to an employee who recommended I put in 20 drops of esstential oil in each chamber because it's so big. Nothing. I tried filling it up only to half of the max fill line with 20 drops and still not a very strong scent. I kind of got used to it and just assumed that's how it was until I bought the AromaOm. I wish I had two of those instead of one of these. That diffuser is infinitely better than this one even without all the bells and whistles. This one was expensive and a waste of money. I wish I could return it.
