It was difficult for me to work in our office as we only used window and floor fans and the room just got so hot it was almost impossible to work. This mini fan/humidifier has already made a difference, allowing me to work more comfortably at my desk. I have found that adding ice cubes to the tank is best and they are very refreshing. The LED lights add a nice touch, especially at night - my daughter noticed them straight away! I will also be using it to cool my side of the bed even though we have windows air conditioning. Lots of punch in a small package and I wish I had had it sooner this summer.
