I love my Curve Single Diffuser. I got the Spa scent and this lovely diffuser is in my bathroom. The design is minimalist, clean, modern. What a clever way to dispense scent into the air. Looking forward to trying the other scents.

First, I will say that this is a beautifully crafted diffuser that is unobtrusive and can be placed almost anywhere. It is very simple to set up and use. The scent I chose is “Spa”. It is nice…a little too sweet for my preference, but does have some citrusy undertones (wish this was the dominant scent). The fragrance is very subtle and I almost don’t notice it until I have been in my bathroom for a few moments. I am hoping to find a scent that I love. My only suggestion, would be to have a sampler…like scratch and smell type cards. It is so difficult to intuit what something smells like with a description. I like the fact that this is not a plug-in, or battery operated diffuser, and dosen’t spout mist…instead it just emits steady scent from the two escape holes and they can be plugged if ever the need arises. Overall, I am very happy with it.

I have had my diffusers for about 6 weeks now, and loving the subtle scent it brings to each room. I've got one in each room all with different scents. My favorite is the tranquility oil. I place the lids on when I leave for trips and so far this has prolonged the oil... still have a few more weeks/month before I need to buy new ones. the design fits with the aesthetic of my house nicely. Would recommend!

The scent and diffuser keeps my small bathroom and hallway area smelling fresh but not overwhelmed.
Looks nice and nothing like a typical plastic air freshener.

It doesn’t really give you enough instructions!
Only smells when lid off?

Hi Kimberly. Yes, the lid is meant to be removed while the diffuser is in use so the scent can disperse. When not in use, the lid can be replaced to help contain the scent. We hope that helps.

Love this diffuser!! I've ordered 3 so far. It's a wonderful concept - no flame, electricity, and you can control the strength of the scent.

The packaging, workmanship, design, quality, function and beauty of this diffuser is the best I’ve ever seen. They also provided over the top excellent customer service that deserves mentioning. Highly recommend this high end product. Looks lovely in our home and we’re very happy with the purchase. Thank you Loon and Stone. Happy customer

So far, mixed feelings. I decided to try the 'home' scent because it was the most popular, but did not care for it at all and it was overpowering. I contacted customer service and they were very accommodating and sent me a different scent free. I chose 'bright orchard' this time and really like it, but must have the diffuser right under your nose to smell it. I may try one more scent to see if this product is going to work for me, but for now I'll say this is a great company with fantastic customer service.

This is so different from anything else out there. It looks beautiful on my desk and the scent is really nice - bright orchard. Definitely a favorite.

I keep this on my nightstand and it's honestly perfect there. I chose the bedtime scent. It's light, calming and isn't overpowering. It feels really good knowing I'm not breathing in synthetic fragrances while I'm sleeping. So glad I found this.

I received my Single Diffuser about one week ago and have enjoyed it each day since. It arrived beautifully packaged and would make a very impressive gift. I selected the "Calm" essential oil and was pleased that the diffusor came "pre-charged" with the fragrance. I poured in the bottle using the provided funnel and the diffusor was working and smelling great immediately. The scent is subtle, not too bold or overwhelming, and the wooden diffusor adds a certain richness and fullness to the fragrance. I keep it open on my desk during the day while I am working and find it very pleasing. It also looks attractive on my desk. I will definitely consider buying a larger diffuser as well as a subscription in the near future.
