PureGuardian Evaporative Travel USB Aroma Diffuser, Essential Oil Diffuser Perfect for On The Go, Use with Your Computer, in Your Car, At The Office, or At Home, Pure Guardian (Pack 1)

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.
