Simply Diffusers Aromatherapy Fan Powered USB Travel Essential Oil Diffuser with reusable pads and LED Lights | Optional Battery Powered | Great for use in the Bathroom, Office or Hotel. BPA Free

This diffuser is very convenient for use in my 7th grade classroom. Instead of heating water, it heats up little cotton circles to produce the aromatherapy. I drop anywhere from 4 - 10 drops of any single essential oil alone or as a mixture to liven up my desk in the mornings. The smell does not travel throughout the room like a normal water diffuser nor does it last that long, which is why I gave this 4 stars; it stays located within a foot or two of the area around this tiny diffuser and only lasts about 2 hours. It doesn't take up much space at all (I have a TINY desk) and it's easy to plug into one USB port of my computer and let it run.

I bought this item to use on my desk at work. I wanted a waterless one so I didn’t have to worry about spills. I really like the size and ease of use. Unfortunately, the fan in the unit is hardly even noticeable. It isn’t strong enough to circulate the scent of the oils around. I’ll be looking for a different one.

I tried out my diffuser using USB power and everything worked fine. I have not tried using batteries yet. the instructions say to use "a few" drops of oil on the pad, then put the pad in the diffuser. I tried it with three drops, but three drops don't seem to be quite enough oil for the pad. I changed the pad and used more than three drops of a different scented oil. Instead of using my one drop-sized measuring spoon for the second go-around, I poured a very small amount of oil onto the pad. I do not have a measure of how much I used, but it did not completely soak the pad by any means. The size of the oil spot on the pad was maybe 1/4 inch diameter. That seems to be enough. I can smell the scent and it is not overpowering. So far, so good!

I bought this for our small bathroom, but it is not strong enough. It is super cute though and works. I moved it to my car.

I have tried a few other diffusers, and this is the best that I have found.

Was a little disappointed how long you could smell the oils

I've only had this for a week or so, but I love it. Easy set up. I can definitely smell the oils, but my work mates aren't getting overwhelmed by the scent. I don't love the light, wish I could turn it off, or stick to one color, but that's a minor inconvenience for something priced right. Really cute in person. People have come by my cube to tell me how cute it is.

Works ok. Cannot control light separately from diffuser
