Beautiful diffuser
I love this diffuse so far. It is elegant, beautiful and switches itself off when it runs out of water. What confuses me is the noise it makes before it starts the diffusion.

Blue Diffuser
Love the color and the wood looking base.

I’ll sometimes put the color lights (my fave is the Blue) at night, even when I’m not diffusing for the ambiance.

Beautiful and easy to use
Beautiful diffuser. I like that it has the option to make the misting intermediate. Lights up beautifully if you choose that option. Holds nice quantity of water. Know that the base is simulated wood.

Excellent customer service.
The diffuser is beautiful and I’ve received many compliments on it. However, after one week of use it began making a very loud sound coming from the motor each time I turned it on I contacted customer service with the problem and they promptly responded. They are sending me a replacement. I am very pleased with their service and am looking forward to my new,quieter diffuser. I understand that sometimes items are defective and don’t fault the company at all. I am happy that they were willing to replace the item without much hassle. Thank you RMO. You have earned my respect and I will continue to be a loyal customer.

Stunning diffuser, fantastic customer service for initial defective item.
This diffuser is stunning. First impression taking it out the box, I wasn’t impressed with how the glass looked. But when I turned on the light feature, keeping it on the white light, it glows brighter, more vibrantly, and in my opinion, more impressively-looking than in the photo. It’s a near identical match to a 6” decorative glass globe I was fortunate to find a couple years ago at TJ Maxx for around $10, so I’m ecstatic on how well they compliment each other. I like that it has the option to rotate colors, stay on one color, as well as to keep the light well as constant diffuse, intermittent, or if you want that feature off for just the decorative light feature. I don’t know how well it diffuses I’m larger rooms, but for an approximately 300 square foot room, it distributes quote well. It’s still new, so I just hope it lasts for a very long time and keeps its quality.

In addition, I originally received this item, and used it right away to test out for about an hour. I shut it off, then was very disappointed that it completely failed to work after that. I contacted Rocky Mountain Oils about it, and as soon as they received my correspondence, they sent a brand new one out to me with expedited shipping, which I really appreciate. Not sure if it’s because I mentioned I was expecting to use it for aromatherapy sessions with clients that week, or if they would’ve expedited it that quickly regardless. I’m really happy on how they handled it, not even asking me to ship the defective one back (which would’ve been quite an inconvenience to me, even though other companies might have done so). Much appreciation to you, Rocky Mountain Oils for supplying such a beautiful item, and for your great customer service.

It looks like on the picture that there are two buttons but the Insteuxfions section suggests there should be three. My main concern is that I be able to have a timer function for this so it doesn’t just run until it runs out of water. Does this have a timer function?
A shopper on Nov 5, 2017
BEST ANSWER: Sorry for the confusion! We have updated the product page and this diffuser only has two operating modes: Continuous and Off.
