Review on 🌬️ QEFUO Portable Bladeless Neck Fan - Upgraded 2021 Version with 360° Air Flow, USB Rechargeable 4000mAh Battery, Hands-Free Operation, 3 Speeds - Ideal Wearable Fan for Travel, Home, or Office by Ryan Draper

This is a decent product and it works, but when it's very hot you won't feel much cooling due to the power of the fans. Obviously it's just a fan pushing air. The harder he presses the colder it gets but it means more power etc. Don't buy this unit and expect AC unit type results, buy it and expect a breeze on your neck. 70 degrees Fahrenheit to 83 degrees Fahrenheit is the sweet spot, while anything above that is the "at least it is something” level. In a cool or cold room, you feel completely relaxed, as if the ice is barely touching your skin.
