Review on Upgrade Hand-Free USB Personal Fan: Portable Headphone Design Neckband Fan with Rainbow & White Light, 3 Speeds, Rechargeable - Perfect for Sports, Travel, and Office (Pink) by Centerfold Montague

This great fan. I've used it while reading a book by the pool and walking on the treadmill. At least, that's what I did, until my boyfriend decided to sneak him in to work with him. He works with the road crew, so always has a fever and a flag or sign in hand. With this fan, he can blow a cool breeze while working. The battery life is excellent. An hour charge is enough for several hours. I thought it would be uncomfortable on the neck but I was wrong. None of us bother at all.
