O2COOL Deluxe Personal Necklace Fan | Hands- Free, Battery Operated Wearable Mini Cooling Device for Beach, Sporting Events, Camping (3 Pack Random Colors)

Q: What's the Battery life?

Depends on the battery you use. I bought 8packs at the Dollar Tree store and they lasted 3 hours if the fan ran continuously. I now buy the 4pack/gold for $1 and they seem to last two days, but I don't run the fan all the time.To me, they are worth wearing when I am so hot that I sweat on my forehead! If you invest in rechargeable batteries, that might be the best solution for constant use.

Q: Would long hair get caught and pulled into the fan?

Yes, if your hair is in fans way it will get caught just like any other hand held fan, being battery operated It should not cause major damage to your hair. Air from fan points up towards your neck and chin but blades are on the front.

Q: Does it blow up and out?

It blows up, the fan on the front intakes and the vent on the top blows up. So if you wear it around your neck with it on you get air blowing up into your face.
