I'm a long-time diffuser user and really enjoy essential oils. When my diffuser when on the fritz, I decided to scale up in luxury and get myself a nebulizer. Really glad I did. This is a really cool machine and unlike my diffuser has fantastic room coverage! In reviewing nebulizer brands I did a lot of research and found that this brand had excellent stakes. Comes very well packaged, works great, and super easy to clean with rubbing alcohol. I would caution that you should really know how to use essential oils before investing in this machine because there is no diluting, a little goes a long way, and so you wouldn't want to accidentally harm anyone in breathing in undiluted oils.
Also, would like to say that shipping was super easy and fast - and really impressed with the organic packing peanuts (very cool that they dissolve!)
