Love my new diffuser!
I absolutely LOVE this diffuser, not only is it beautiful but uses tap water only, not distilled like a lot of diffusers I’ve had. Thinking of buying another one for another pet of the house!

I love the diffuser. It is the first one that I have used that is easy to put the water into it without spreading drops as you take the top off.

I love rocky Mountain oil products and have purchased from RMO frequently but will have to stop as they are charging exorbitant amounts for postage.

How does this difuser difuse the oil? Is it hot or cold?
Jessica.hopwil on Dec 28, 2017
BEST ANSWER: This diffuser is considered an Ultrasonic Diffuser that doesn't use heat or cold. Using a diffuser is easy: Fill the diffuser with water to the recommended line, put 5-10 drops (more or less as needed) into the diffuser and then turn it on. The ultrasonic technology produces vibrations at a high frequency, turning the water into mist. As you breathe in the aromatic mist, the oil's beneficial properties are immediately absorbed into your body.

I just got mine in the mail, there is a think soft plastic between the glass top and the unit do I remove this once I get it or does it need to stay there?
A shopper on Jan 29, 2018
BEST ANSWER: Great question! The rubber lining is to help cushion the glass top.

How long are the intermittent cycles and does it spray better than the other diffuser that you sell (the white one) that some are saying has a small opening and does not release much scent?
