This little gem came in handy the very first day I received it, because we had bad weather and the electricity went out! The mini air conditioner provided cool air and lighting, which helped me sleep. I wasn't expecting much, but I was really surprised by how much air flowed from such a small device. I first tried it without pouring any water into it after removing it from the box. I started at the lowest speed and went all the way to the highest, and I thought it was sufficient for such a small device. I then poured water into the container, tested the misting function, and was pleasantly surprised by how comfortable it was. I next played around with the lights because by now it was getting darker inside with the electricity out. The light function was bright enough for me to move around without bumping into anything. This device also comes in other colors besides the white light, which is pretty cool. Plus, you can set the fan to auto-shut off in 1-6 hours if you wish.
For the price, this is a pretty awesome air cooler, and I do not think a buyer of this unit will be disappointed. I am very satisfied with the unit. I received this unit free for my honest opinion.
