Review on 5200mAh Battery Powered Neckband Fan - Hands-Free Portable Personal Fan for Sports, Home, Office, Travel - 4 Speeds, Natural Wind Mode, 360° Adjustable (Pink) by Rosalio Zavala

I work outside in the heat of summer and wanted to try this because all the landscapers said it was great. It works for a long time, and the fan speed is adjustable and has a gooseneck position. The problem is that the part that lies in the neck is hard and inflexible. After about 10 minutes, my neck starts to hurt so that it no longer cools my head. Also, it doesn't slip/stay in place. I can try wrapping the hard part of the neck in something soft and grippy. Although I think the manufacturer might have thought about that before selling it.
