Light weight, portable air cooling fan only bought 6 months ago and only used for a week. There's nothing wrong with it, I just needed something bigger to cool off a bedroom. Going by reviews, it's great for camping or a small space like an office. 700ml water tank, 7 different light modes. Adjustable wind direction, 4 wind speed. USB multiple charging methods. Weighs less than 2lbs, 6.25 × 7 × 10 inches. There was a review that I thought was helpful! They said while camping. They put ice cubes in every morning and by bedtime they were almost melted which made the water colder. It's ok to run while it still has ice cubes in the water too.
