Quamii Aromatherapy Essential Oil Diffuser - 400ml Ultrasonic Cool Mist Aroma Humidifier with 7 Color Changing LED Lights, Adjustable Mist Mode and Waterless Auto Shut-Off (Dark Bamboo Woodgrain)

So far, so good! I just got this going and I love the scent it adds to the room. I'm using it in a room that has 19' ceilings and it about 30' x 15' and I have the mist on 'high.' I can easily smell the oil all over the room! I selected this one because of the reviews, and I thought that people commented (or answered questions) that they could NOT hear this unit running. Well, I can hear it from hear it from across the room. It's not an annoying or loud sound, but I do hear a low shhhhhhhhhh or bbbbbzzzzzzzzzzz noise (it might even be a sort of low, dull fan noise). It might actually be a nice white-noise sound while trying to sleep...may need to try that! I like the look of it...has a dark, wood-grain look, but it's a slick, smooth plastic. I love the option of having the lights cycle through colors (white, red, pink, purple, blue, green); they are really nice and slowly morph from one color to the next. The white power cord is about 6'2" long, so plenty of length for my purposes. Also, there is a nice flow of mist coming from it. The picture next to this review is a bit exaggerated when compared to my unit. But if mine could fill my very large room in a matter of about 5 minutes, it's doing a great job! Highly recommend it!

I have been using this same diffuser with a different label for a few years and am glad I found the Quamii 400ml unit on Amazon. The size of the diffuser allows me to use it all night while I sleep which is a good thing. I like having the choice to use rotating colors, a single color or no light at all (which is what I do most of the time). Another benefit which is very important to me is this diffuser can use citrus based essential oils... some other brands are not able to do this. All in all, this is a diffuser I am very satisfied with as it has given me no problems and is identical to what I've been using for quite awhile. I gave the scent rating 4 stars but that is a reflection of the essential oils I've been using and not the diffuser... it does a good job of dispersing the mist into our bedroom.It's a good unit and you won't be disappointed if you decide to buy this one.

This is a great little diffuser, pretty quiet and has an auto shut off when the water gets low. I use high quality essence oils (Dōterra) and it makes a difference that I can smell it throughout a 600 sf area of the open plan area of my home. The instructions say to use 3 to 5 drops per 100 ml and it is about a 350 ml unit, I only use 10 drops and this little diffuser disperses the scent very well. The lights are lovely, they can either cycle through all the colors, set to be on only one color of your choosing or shut off entirely. There are no annoying indicator lights either. When the water runs low and the auto shut off kicks in, there are no annoying beeps or sounds. This little unit is easy to set it and forget it with no worries. The only drawback of the unit is that the top can be a little cumbersome to get off to refill, I wish the mfg had put a little finger indentation of some sort at the back of the unit to allow easier lift off. The top doesn't snap on so if a toddler or a cat were to bump it and knock the unit over, I'm sure it would create a mess but you still need to work at it a little bit to find a groove of some sort to lift the top off, that is the only reason I knocked one star off. The on / off button is camouflaged very well, this can be a pro or a con. The button doesn't distract from the simple beauty of the unit but it blends in so well that my husband couldn't see it to figure out how to turn it on (I will give him credit though that the room wasn't brightly lit at the time). I haven't had any problems with dripping, condensation or overheating (the unit doesn't get warm at all). It has a low and high setting to dispense the scent although I couldn't tell that big of a difference between the two. I've run the unit for 5 to 6 hours without any problems, it could probably run longer than that before running out. I run it for a few hours before I leave for work and when I get home, refilling it as necessary. I empty it entirely and wipe it down with a paper towel and Q-tips to get in the grooves. A little vinegar and water does a great job for cleaning. I would definitely buy the unit again and this vendor did a great job getting the unit shipped quickly, I had it in my home within four days of order. I'm thinking of ordering another one for my bedroom.

This is fantastic! I was worried that the scent would not be so faint that I wouldn't notice it, but it is very strong without being overwhelming. Sort of like when you walk into a house and you know that someone had been cooking or baking. I used 10 drops of peppermint oil and placed it in my bathroom with the door open. (My bedroom is being remodeled and I haven't tested the product in there yet). I prefer this diffuser over a candle because the essential oils don't give off that artificial smell and it is so relaxing and calming. I am concerned that it is a little too loud for me to fall asleep with while its running. I have a very difficult time falling asleep when there is any noise, so those of you who fall asleep without issue, don't worry about it! It sounds like an electric fan whirring/buzzing. I do like that it is a constant noise so that I can get used to it instead of it kicking on and off throughout the cycle. Overall, I am really glad I purchased this item and will likely be recommending it to others.I received this item at a discounted price in exchange for my honest review. In no way does this effect my review on this product, and I will always provide my honest thoughts and feelings about the products I review.
