O2COOL 3.5 inch Deluxe Personal Rechargeable Necklace Fan for Cooling, 3 Speed Vertical Air Flow, Black

My son has Epilepsy, heat is a huge trigger for him. This fan is around his neck at school, it's small but mighty. He uses it on the bus ride without issue also. Trying to stay active can be a challenge in this hot, humid weather but this little fan goes wherever he goes. He has dropped it several times and it still works. It does have a little noise to it especially on high but it's no problem. I love the battery life it reassures me he will have the cooling help he needs when he is away from home.

I liked recharge tho it takes several hours but no batteries. i have yhe battery type too. good as you can just pop new batteries and back to cooling you faster. both are great help if the heat tries to take you out. bring a spray to make it lkke super cooling.
