I love the Solo diffuser. I am ordering two more. The scents are fabulous and long lasting.

I really like the new Solo diffuser! The Piezo "Squair" is fine for a bathroom or other small space, but the Solo is much better for larger rooms such as a kitchen or living room. It is also nice to have 3 levels of diffusion and a light. My Solo has worked well for the 3 weeks I've had it and I plan to buy another. Great mid-size option between the Squair and commercial size diffuser.

This is the most amazing solo & piezo diffuser I have ever owned! Not only is it decorative and modern looking, the size of it works anywhere in my condo. The eucalyptus lavender scent diffuses such a light but airy scent throughout my open condo. I even took it down to Florida to continue enjoying the gentle smell. At-Aroma USA is the only company I will ever purchase these products from again. Not only does the true aroma oil last a long time in the diffuser, it is so easy to fill. I really like the lighting on it also. Thank you At-Aroma USA for the opportunity to own a true diffuser with pure natural oil.??

This is a great product and a must have to refresh a home's stagnant air. We have been using the aroma therapy diffuser for a few weeks as a way to create a more relaxing home environment. The product does that and more. It quietly diffuses refreshing natural oil at three different rates, making our home air clean, pleasant, and refreshing. The natural oil therapy helps us focus when we telework and relax when we do our home meditation practice.

This is the diffuser I have been holding out for. As a longtime user of your oils (please don't ever discontinue scent of tokyo > cool gray > grayish wood), I'm so happy you have come out with a diffuser as thoughtfully designed as your other products. It not only works perfectly, but it looks beautiful as well. The matte white, bluish clear container and the soft glow make this object settle unobtrusively into any corner of the room. Nothing extraneous, every piece is simple and timeless.
