Review on YZHI Neckband Rechargeable Personal Portable by Brandie Zhang

Works well, stays charged for a limited time. It's supposed to provide cooling, but my problem is that the part that charges and is intended for the neck gets very hot during use. I don't know if mine is defective or if it happens with every device. If your main goal is a light breeze, then this will work. If you're trying to combat heatwaves, definitely choose another option.
