Review on O2COOL Rechargeable Necklace Fan Adjustable by Kelly Sadiq

Not a bad product for the price. It's lightweight, rechargeable (one charge lasts several hours), but don't expect it to keep you cool on very hot days. It doesn't have enough power to blow air in your face while hanging around your neck. Most of it goes in the neck area. A little loud but not loud enough for others to hear. The material looks cheap, don't know how long it will last.
