  • Oil Diffuser

    I like the diffuser... My only problem with it is I have to refill it to often... Other than that it's ok...

  • Nice

    Have used the product once so far. Pleasing to the eye. Cover was a challenge to remove at first. Net layer can be a little challenging to open too. Stick with it and you will get it. Directions aren't much help in opening it up. Once you get it open and filled, it works as described and puts off a nice mist. Light is a little bright but not too bad. Could bother some. Overall I will enjoy this product and it is exactly what I was looking for.

  • Broke just after a few uses

    Item won't turn on anymore. When it did turn on it worked fine. The directions on the box are not very user friendly

  • Interesting!

    I liked it enough to order two but wanted to point out a few things. They are smaller than I thought so make sure to read the description for size (I did not). It truly is for your "personal" space or a small room (like the size of a bathroom). It does turn off on it's own but it turns off when there is a substantial amount of water left in the resevoir. So it makes me wonder about bacteria build up if there is always a good amount of water left. Also the cap is not very easy to get off. So you must be extremely careful when trying to get the cap off to refill as there will be quite a bit of water left that can be spilled when trying to wrestle the cap off. Overall, its a great price for a diffuser, they are pretty, and the light effect it gives is nice. I have ordered a black one and wonder if it will glow like the white???

  • 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.

  • 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.

  • 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!

  • What is the water capacity/volume? How long will this diffuse? And what room size measurements are suggested?

    • Hi, rama1. The water capacity of this diffuser is 135 mL (about 4.5 fluid ounces). Depending on what setting you have it on, it will diffuse for 3 to 5.5 hours. This is considered a personal-sized diffuser and is meant for use in a small room like a bedroom, an office, or a small living room. Thank you for shopping with us, and have a great day.
