Product review (5 stars): Great for Small Spaces & Personal Use
I was provided this free sample for my review. I've been using the Flyimei Diffuser in my home office desk for the last couple of days and I must admit I was skeptical about its effectiveness being a Dry-air diffuser which does not use water like other standard water based diffusers.

But despite its small size and being non-water based works surprisingly well. It consists of a small Cotton/Felt pad ( there are 3 supplied in the box) under which there is a small fan which helps diffusing the fragrance into the air. It works very well for small spaces like office desks and can even work for larger rooms provided you give it a couple of hours . The ability to run it via a standard Micro USB  connector or batteries  is is a real plus as  I already have my phone charger  at my office desk & nightstand and don't have to worry about connecting yet another cable .

The Good
- If you don't like the humidity created by standard water based diffusers than this dry diffuser is a perfect alternative
- More Hygiene - Water based diffusers need to be cleaned regularly to prevent mold buildup
- Works surprisingly well despite its small size
- Looks very nice while using any of the light modes ( 8 Solid colors or pulsing light with all colors)
- Ability to be powered by a standard Micro USB phone cable or Batteries
- Ultra Quiet - Even in pin drop silence you can barely hear the fan running

The Not so Good
- Optimum effect lasts for about 3-4 hours after which you need to add a couple of drops of fragrance/oil again
- The felt pads will have to be replaced if they get worn out

Important Consideration
- Since this is a dry diffuser the quality of your Fragrance / Essential oil will matter a lot for best performance. Cheaper oils may not diffuse that well with this dry diffuser
