Review on O2COOL Rechargeable Necklace Fan Adjustable by Michael Tran

Finally after a delay in delivery and then a mistake by my last postman. I finally got my O2COOL chain fan from my neighbor. The fan is ok but a bit noisy and the air only comes out of the top vents. I was hoping it came from a real little fan and vent. I was going to return it but decided to keep it because the necklace feature will come in handy when you go, also I prefer other small portable fans because they are quiet and have many features.
