Review on Efficient Mini Air Conditioner Fan with 4000mAh Battery & Remote - Personal Air Cooler (Deep Blue) by William Lopez

It was useless. This is a very small $60 fan. The monitor kept showing that there was not enough water, even though I filled it according to the instructions. Don't waste your time and money. I sent it back immediately and am still exhausted from the heat in my very small office. Don't buy this. It's useless. Unless you want a $60 mini fan.
