Excellent device

Verified Purchase

Excellent dispenser, slightly smaller than expected, but does the job great. The steam jet is strong, easy and simple to use and operate, connecting to a USB cable, filling with water to the marked line, and a few drops of your favorite essential oil, the device works with several options for changing lights. I use it regularly in my living room to create a sense of calm and a pleasant and relaxing atmosphere. My favorite essential oils are lemongrass oil and geranium oil from naw.

A compact assistant for concentration and comfort

Verified Purchase

The NOW Foods USB diffuser is the perfect gadget for creating an "iHerb spa" atmosphere right on your desk or in your car. It's compact, minimalist, and incredibly easy to use. This diffuser has become the perfect addition to my desk. It's compact, takes up minimal space, and is USB-powered. You can connect it directly to your laptop or power bank. It operates silently and produces a fine, cool mist. A couple of drops of peppermint or lemon essential oil are enough to refresh your thoughts while working. It features a soft color change that's not distracting, but rather relaxing. It's perfect for creating a cozy atmosphere in the evening. It's easy to clean and refill. Unlike larger stationary models, this one is easily moved from room to room or taken on trips. It has an auto-off feature when the water runs low, so you don't have to worry about forgetting to turn it off before leaving. The high-quality plastic (BPA-free) eliminates any odor, leaving only the scent of your essential oils. For an area of 10-15 square meters, the power is quite sufficient. A quick maintenance tip: to ensure the diffuser lasts a long time, use purified or distilled water. Be sure to wipe the inner ultrasonic plate once a week with a cotton swab dipped in vinegar—this will remove limescale and maintain maximum spray power!

Aromatherapy anywhere with a USB! The NOW USB diffuser is highly recommended for its portability and soothing effects.

Verified Purchase

I bought a NOW Solutions USB oil diffuser and have been using it on my desk every day! First of all, the fragrance diffusion is fantastic. The ultrasonic technology creates a fine mist without heat, allowing the essential oils to truly shine. Adding 3-5 drops of lavender or eucalyptus gently diffuses the diffuser throughout the room, calming my mood and helping me focus. (It covers 200-400 sq. ft., making it perfect for small rooms or my office desk!) It's incredibly convenient. I can plug it into my laptop, power bank, or car charger via USB, so I use it on business trips and in the car. At home, I plug it into my desktop. It has an auto-off feature that automatically shuts off when the water runs out, making it safe for anyone, even beginners. As expected from the NOW brand, the BPA-free plastic is odor-free and durable. It's compact and lightweight (it holds a 70ml water bottle), making it a travel essential. The neat packaging makes it a great gift, too. The scent lasts for 4-6 hours on continuous mode, making it perfect for leaving on all day. The LED light gently changes from red to green to blue, creating a truly captivating atmosphere. It's also whisper-quiet, so it won't distract you from focusing. The only downside is the small water tank, which means you'll need to refill it frequently, but that actually keeps the water fresh. It's the best value for money, so I'd definitely buy it again! For anyone who loves aromatherapy or wants to change the mood at their desk, I highly recommend this USB diffuser! 🌿✨

Excellent

Verified Purchase

I've had it for 5 years and it's still working perfectly. It's of excellent quality and uses great. The scent is refreshing and it also humidifies the air. The fragrance diffuses easily. It's a medium size, tending towards small. Its benefits include pleasant scents, an air humidifier, and when I'm sick, I add a few drops of Vicks VapoRub to help with breathing and soothe a cough.

The size is considered small, but its quality is good. I liked it. It had a slight defect that made it not close for me, but in general, the fragrance is good for its quality.

So cute! Works great!

Verified Purchase

I am really pleased with this little diffuser! The online pictures make it seem a lot bigger. But, it's small and cute. Light as a feather, and the optional rotating light colors are a nice feature. I put the ArtNaturals lemon oil in it that I got in an iHerb Exclusive beauty sample kit and it smells so good! Easy to use and I like the looks of this diffuser compared to others online. Highly recommend.
