Droplet Diffuser
I am very pleased with the Droplet Diffuser. It is sitting by my computer diffusing away with Lavender, Orange, and Geranium. It is definitely for small spaces and nice to have nearby and nice to look at.

Works well
I don't know how long it will last, but so far we are enjoying our Droplet diffuser. During power outages it has come in handy to replace our nebulizer for our baby as we can plug it into a rechargeable lithium ion power pack (typically used for charging phones on camping trips). No essential oils for Baby!
For adults it did well in an average sized living room diffusing Pumpkin Spice Latte essential oil blend. Delicious smelling & very calming.

Good value for the money.
I bought some cheaper versions off Amazon but they would make weird noises and were very difficult to clean. It also became very hard to get the kids off the cheaper versions. This one lasts MUCH longer throughout the night. (We use these for our kids bedrooms). We only have to fill it up every other day! Definitely worth the extra money.

I would definitely recommend this product! It is light and functional and I love the rotating lights. It comes with a cord that will plug into your computer, and is functional and can be used in a normal Outlet with the use of an inexpensive Outlet adapter. I have found that if it is overfilled, aside from the fact that you could spill water and essential oil, overfilling reduces the functionality of the entire product. When it is overfilled the vapor is decreased. When I first got it in the mail, I filled it up plug it in, and it provided a Heavenly smell, throughout my living room 17ft x 22ft and kitchen, 17ft x 12ft. Until I knock it off the couch side table, (when raising the blinds on the picture window in the living room) after which point it started operating at only half proficiency. But now it's perfect for my bathroom. It's easy to use, Easy to fill, lasts most of the day, and adds A Touch of Class and modern Beauty to whatever room I put it in. I plan to order another one as soon as I can get the money together. (I'm a 68 year old truck driver living alone at 9000 feet in the Colorado Rockies).

Small but mighty!
I first bought 2 of these for my son and I. I just ordered 2 more to replace other diffusers that don't work so well that I had bought from Amazon. They are priced perfectly! I use mine by my bed and it lasts for 2 nights! I also love how the color is so vibrant! Definitely my favorite diffuser! I love everything that I've ordered from Rocky Mountain oils and have never had a problem. Their oils are amazing!

mainegirl16 on Jan 26, 2019
BEST ANSWER: Great question! It should be in the closed position. You may remove it to be able to clean the metal plate below, if you choose to do so we advise using extreme caution and care to not damage the plate.

Can I use the non-neat oil blends in this diffuser or do I need to use the neat versions of oils that do not have the carrier oils in them?

BEST ANSWER: Many of the blends are still able to be diffused, FCO is a thin carrier oil that does not cause an issue when diffusing. There are however some blends or oils that are too thick to diffuse such as Vetiver.
We recommend only diffusing the oils with a diffusion icon on the label.

I’m completely new to essential oils. How should I use this? Do I add the water then put in my oil? I’ve checked and my oil can be diffused. If so any suggestion for how many drops to use? Do I use the carrier oil I purchased ( FCO) and add the essential oils to that instead of water? Thank you.
gerrie b on Jan 9, 2019
BEST ANSWER: Great question! You will fill the diffuser with water to the fill line marked inside. You may add 5-10 drops of essential oils to the water depending on personal preference. You do not need to dilute the oils before adding them to water.

I love this little diffuser, but can't figure out what the open/close switch is at the bottom of the well. It's probably obvious, but I can't figure it out and it's not mentioned in the pamphlet that comes with it. What does it do?
Pauletta S on Aug 8, 2018
BEST ANSWER: Thank you for your question! This switch is only used for cleaning purposes. If you are not cleaning your diffuser, please be sure to leave it closed.

How easy is it to take apart and clean thoroughly?
A shopper on May 22, 2018
