   I was dubious about how effectively this little diffuser would work. I have it plugged into my computer now with Thieves on the diffusing pad. It is amazing how quickly it fills up the large room that contains my desk with the scent of Thieves–not overwhelming, but strong enough that if I had another person in my office, I’d need to ask their permission before using. If the scent starts to get too strong, I turn it off. I don’t have another diffuser, so I can’t compare, but I do like this.

   This diffuser works by means of what I assume is a very quiet fan that circulates air around the pad. I showed a photograph of it plugged into my computer so you can see its size. There is a credit-card sized gift card sitting on the desk in front of it as a size comparison.

   Very small in size. It’s about the size of a lemon. You put a few drops of your favorite essential oil blend onto one of the pads that are provided and plug it in to the USB port of your computer. You can hear the fan working as it moves air across the oil on the pad and diffuses the fragrance. For me, it’s a bit too much to have it running on the laptop while I’m using it. I wouldn’t want to use it in an enclosed space, like a car, either. You’d want to keep track of the pads you use because I don’t think you can get more. It’s a little gimmicky, but still works effectively.

   This is a nice little diffuser. It fits in the palm of your hand but puts out enough of a scent to fill a large vehicle or small room. I’m using it in our big passenger van since it has USB outlets in just the right spot low den on the dash. It’s a nice change from car air freshener sand I feel better about using natural oils rather than chemical fragrances. I’ve also used it with a power bank for when I’d like to have lavender oil on the nightstand but would rather not have to move or fill the regular diffuser.

   The usb was super flimsy and just stopped working within a month.

   While it is not a large container for aroma therapy, it’s small size is what makes it ideal as a travel companion when you want to have aromatherapy on the go…plug it into your portable laptop or USB outlet in a wall and you’re good to go for a couple of hours!

   At a couple of hours, however, it definitely doesn’t have the endurance for “extended use.” But its portability lends itself to fitting quite well along with your luggage and you can enjoy it wherever you are if you need something to soothe your nerves.
