Smiley Daisy is such a happy name. And Smiley Daisy, a small company specializing in aromatherapy devices, clearly wants its users to be happy. Even their website is happy. (The About Us page is downright giddy.) The Smiley Daisy Ultrasonic is full of cheerful features. Not only does it diffuse luscious herbal aromas into the air, but it's also a humidifier and an ionizer, so it will unclog your sinuses, smooth your dry skin, put you in a gloriously good mood and help you sleep. If you're not happier after using it, you should ask for your money back.
Let's look at the Smiley Daisy Ultrasonic in more detail. As its name implies, it uses ultrasound to diffuse essential oils (oils distilled from the essence of exotic plants) into the surrounding air. Some people claim that these aromas will alleviate your stress and make you happier all by themselves. Not content just to be an aromatherapy device, though, the Ultrasonic also includes an ionizer, which fills the air with negatively charged molecules, which have been demonstrated in hospitals to scour germs out of the environment and which some people feel can alleviate stress and headaches as well as help you sleep better. And as if that wasn't enough, it's a humidifier, producing water vapor that can clean germs out of the air and unclog your stuffy sinuses, especially if you live in a cold, dry environment. In case we haven't mentioned it yet, it also glows in changing LED colors.
You're probably feeling happier just reading about all this, so clearly Smiley Daisy's work is partly done. (Grumpy skeptics might want to check out a different section of this site, because you're really harshing Smiley Daisy's mellow.) Amazon users love this little gadget, except for the one who found that the cap became fused to the unit after two weeks use. (You do have to clean it occasionally.) It's inexpensive, too, and not spending money is one of the happiest things you can not do. Still, if you aren't convinced that this is the oil diffuser you want, take a look at the Aromyst Ultrasonic Glass, the Welledia Wellspring and the Viva Naturals Tranquil.
Awesome little diffuser for personal use...is very quiet...I'm amazed that it really only takes 3-4 drops of high quality essential oils for a fabulous aroma.
It's awkward to open, especially if there is still water in it, and awkward to close to make sure you don't spill any water...also a bit louder than I though it would be.
This gets the job done...works great! What I love the most is that you can turn the light off on this. Easy to clean. One year in and no trouble at all.
Purchased 3 of these about 6 months ago. None of them are working now. It was very difficult to get the top off. Then, after a few months they just stopped working.
