Pros: I bought this on a Newegg Flash sale. It is a well made diffuser! I have had some in the past that hasn't really lived up to the box pictures, so to speak. This one has a good, barely visible, steady stream of mist. The oils are noticed immediately, The LEDs were a very nice surprise, as they are rich in in color and very bold! Really, they should have a few more pictures showing different color examples they cycle through. They aren't intrusive ina dark room and bright enough to be seen well in a fully lit room!

Cons: No battery compartment for flexibilty, but that's what you get for its small size.

Other Thoughts: The LED lights, when cycling through, can be paused on a color of your choice if you would like a single color to display only. There is also a feature to spray intermittenly, or you can keep it on, for which it will shut off automatically after 6 hours continuous use. (Should pretty much expend its full reservoir of 500mL). Both nice features! Good job, Aukey.

Pros: Almost all of the diffusers I’ve seen spill (usually spilling all of the stored water), when they fall over.

This glass model (it’s worth noting that the second best model I’ve seen was a similar style glass model), is high quality and has a secure lock.

The tip to the tank to release the mist and diffused oils (if you place some inside), into the air is perfectly placed with the top of the spout positioned just a fraction of a centimeter below the brim of the surrounding glass.

This diffuser works great not only as an ultrasonic humidifier / air purifier but also for aromatherapy. If your sinuses bother you, a few drops of peppermint essential oil or orange essential oil placed bedside (by your head so the mist come up near your face), could make a world of difference. It also might not depending on the reason for you sinus problems but breathing in certain essential oils is very well established with helping many people clear out there sinuses.

Due to its sleek, modern, glass design, it should look great, just about anywhere you place it.

The 7 colors are easy to select your desired color. I would’ve preferred a simple press to cycle but the way it works is pretty cool but you can actually pick way more than 7 colors. Once you press the light button the light will go through a spectrum of R/G/B color combinations. When you see what you like, just press the light button and it will remain the color it is at the time you pressed the light button. It always follows the same pattern so your favorite color/s will be easy to locate through memory with a couple of uses.

Cons: Nothing that I noticed. I wish the tank was 300ml but for what it is, I love it.

Other Thoughts: Make this glass model with a larger tank.
