Review on Stay Cool and Hands-Free with our USB Rechargeable Outdoor Personal Fan - 360 🌬️ Degree Rotation, 3 Adjustable Speeds, Headphone Design Neckband Cooler - Perfect for Travel, Sports, Office, Camping by Danny Kimble

I'm not quite sure why there is heat ☆. But it definitely cools very well. The fan tends to slip around your neck when you use your hands. My hair was in a ponytail and he slid and sucked my hair right in. There are a few speed settings. Right next to this button is the button that will change the color of the bubbles. It is very convenient to use at night. The sleeves that hold the fans are flexible and can be adjusted to fit your needs. Everyone I've worked at has been shocked at how cool and practical it is. Wear a mask all day, it's nice to breathe cool air.
