Product review (4 stars): Like it but wish USB actually charged diffuser
Cute, small could use in car and plug into USB charger. Battery life very short if you go that way. I wanted it for a tiny bathroom that has no fan but has a window. There are also no outlets in the bathroom. Nice dispersion of pad is saturated. Wish battery life was longer. I thought the USB charged the diffuse so when you unplug it the diffuser would run and battery is back up. Not the case.
