Review on Portable Neck Fan with 2600mAh Battery, Ultra Quiet Hands-Free USB Fan, Strong Wind, 6 Speeds, 360° Adjustable Wearable Personal Fan for Home Office Outdoor Travel (Black) by Jeff Jackson

I got this for my aerospace company, job in California so it's going to be pretty hot. It lasted all day at work where I work 10 hours a day. At first I thought they would be heavy, but they wore them all day and didn't even feel them. Keeps me cool with a nice breeze to them. Fast load time which is good. Included video and photos. Place the paper on the fan to see and also see my hair moving with it to give an idea of the wind.
