I live in southern Georgia where mosquitoes take center stage and fly into your eyes and ears all the time when you are outside. This fan is needed to move air around your face and ears to keep mosquitoes from getting into your ears, nose, mouth or eyes. Inexpensive pest control system. The batteries last 2 hours, so you have to watch when you really need it. Ideal for hunting as the engines are silent. If you are in a forest with pests flying around your face, this will help keep them away.
