Safer than oil burners and gentler to the senses than applying oils to the skin, this aromatherapy diffuser releases small amounts of essential oils into the room according to your specifications.

  • works great!

    a simple and easy to use aroma diffuser. add essential oil to the water and put the lid back on. i do wish it holds a bit more water but for the design, it's great and easy to use.

  • works great and looks great!

    The diffuser works very well. The fragrances room quickly and nicely The design (look wise is pretty good) and is just like the one in the picture. Actually atomizes like in photo only one negative - it could come with better instructions. They are quite bad but you can figure it out. The lid comes off with a 1/4 inch twist and then lift.

  • Pleased

    Diffuser is smaller than I thought it would be, and didn't come with very thorough instructions. I had to go to the manufacturers website, which was on the side of the packaging, in order to find out about the settings. But once I figured out how to use it, I am very pleased with how well it runs and diffuses my essential oils. I love the dark wood style, it compliments my decor much better than the white diffusers I've used in the past. Ordering more soon!

    I bought two of these and love them. They last a lot longer than most others I've found and the "wood" look is nice in our space. Non obtrusive, but gets the job done.
