O2COOL Portable Necklace Fan - Hands-Free Personal Cooling Fan with USB Rechargeable Battery - Perfect for Outdoor, Travel, Gym & Summer Activities (Orange)

These are such good running fans. I love the cool orange color. I run mine on Energizer rechargeable batteries. I have been using these fans since they first came out and they last. I run mine to the point I had to take it apart to clean the dirty blower wheel. I only had one quite on me, but it was used 3 years running it every day during the summer. I wore it out! I never wear mine, I hold it in my hand when watching TV. I keep AC turned up to save power and wear on an old unit. I have had other fans and these are the best. Not too strong or weak. Low noise makes it be able use during TV shows without drowning out the sound, especially now they put better motors in the later ones.
