Aroma-Whisper Waterless Diffuser for Essential Oil Atomizer Made in USA 110V Essential Oil, Fragrance Diffuser Machine for House, Air Diffuser for Home Scent System - White by Diffuser World

I give it four starts because it is SO expensive. BUT it works very well. I like that I can regulate the intervals for how many minutes it runs and how many minutes it is off. I use it for Young Living essential oils and it is amazing to me the healing effect of aroma therapy, using authentic, top quality oils. They are calming, mood altering, and I highly recommend using good quality essential oils to sooth and ease your nervous system.

I'm not sure about the diffuser. I thought that I would be able to smell the oil still when it is diffused, but I can hardly smell the essential oil. I have to put my nose right up to the nozzle to smell it even when I've been away and come back into the room. I also have a lamp diffuser, which puts out a heavy scent, so I was expecting this to at least put out some scent. I keep wondering if it is working properly. Perhaps I just need to be more educated on how the different diffusers work.

Our family had loved our diffuser, but I had somehow mushed the O Ring. Then it started leaking and using essential oils in less than a week. After I diagnosed the problem, the good people at Diffuser World (strangers, a thousand miles away) sent me a replacement O Ring. It fit. Now, the diffuser is as good as new and works perfectly. It is a huge enhancement to the sweetness of an 800 square foot basement in a 110+ year old house. You can imagine.

I like the bottle being separated from the motor, lessening the possibility of damaging the inner workings by getting oil into it. This happened with two diffusers of a different style where the bottle of oil is attached to the part with the motor, and can't find out where to have them repaired. I use essential oils a lot especially for controlling mold in a basement storage area and family room, so this was well worth the cost.

I have used many atomizers and nebulizers in my commercial space, this is by far the least effective I have experienced to date.

This did not meet my expectations. Returned for a refund.

Fabulous diffuser. Very quiet and love the control of the on off setting.

quality product, does what it's suppose to do.
