Buttons get stuck
The buttons are all stuck and I have to unplug it to get it to turn off. The lights and the timer buttons don't work either. It was neat when it worked as advertised.

Buttons would not work
I’m mostly giving this 1 star because the buttons on my diffuser kept getting stuck. I finally gave up and had to unplug it to turn it off. The diffuser is very pretty and I loved that it has an intermittent option on it. The water reservoir is not really big however that is stated in the product details. I would have liked it to put off a stronger aroma, I felt like I had to put a lot of drops in, at least more than the recommended. That could however simply be personal preference. For a small space I think it would be great. It is possible mine was just a defect, but unfortunately I had to return it. The return process was very easy and customer service was as quick to respond. I love all my oils I buy through RMO, the diffuser, was just not a win.

I’m not 100% sold on it yet.
It arrived scratched up a little, but I don’t think it affects the operation. I was disappointed because it looked so much better in the picture. I do like the glass top and the lights seems more subdued than other diffusers we’ve tried so that part I do like. So we’ll see how it does over time.
Wasn’t too happy that it arrived kind of scratched up, but it doesn’t affect the operation.

It's a nice looking unit, but in the one I received the hole of one of the buttons was too small and the button would get stuck when pressed (it slooooowly extends by itself). I hope with time it will get better.

Didn't work correctly
My diffuser constantly glitched and did not work correctly. RMO was awesome, though, and refunded me for the defective diffuser. 5 stars for customer service
February 28, 2018
I do love this diffuser and it’s very beautiful. Only 4 stars because it was wobbly one of the plastic nobs underneath is not the same as the others causing it to be unstable. I did contact Rocky Mountain oils about This they offered to send a return label and when they received it would send a new one, this obviously makes complete sense but since I was dealing with all of us being super sick so I really didn’t want to be out a diffuser for however long it would take for this process and decided to keep the wobbly diffuser. So that’s where I’m at. It is beautiful though. But $60 is a lot to end up with an unstable diffuser.

My favorite diffuser
It's quiet, it looks beautiful, it's the perfect size (medium), and it actually diffuses the oils quite nicely.

I'm glad to have found this diffuser. Highly recommend it!

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?
lori s on Oct 30, 2017
