Love the size of this diffuser, perfect for the office, right? Worked well initially. Now it won't diffuse intermittently and it won't diffuse constantly either. It's still "working" but not as it should. Cleaned it today and changed the wick and it was no different!

You get what you pay for, and this cheap little diffuser is no different. I used it about 6 times before it stopped working. I reached out to customer service and they just kept telling me to clean it. Obviously I tried that, still doesn't work. Don't waste your lunch money on this! (Posted on 1/23/2017)

Sometimes it seems to work and sometimes not. I have it in my car in the cig lighter. I thought it would have a continuous flow but I have to push the side button everytime I want it to diffuse for a few seconds. Is this how it's supposed to work? Still love it though. It's so cute.

I just love my mini diffuser! So nice to have it going while I work on my computer. I just plug it in the the USB outlet and, voila! A nice cool mist of aromatherapy pours out. My rating would have been a 5, but the product info said it would mist for up to 6 hours. Seems that it runs intermittently, and only lasts about an hour. (Posted on 1/16/2017)
