Review on 🌀 Stay Cool on the Go with Portable Neck Fan – USB Rechargeable, Hands-Free Mini Fans for Personal Cooling, 360 Degree Rotation – Perfect for Travel, Sports, Office – Black by Walter Devarakonda

This fan is actually very good as it is very tight around the neck and adjustable. There are 3 speed modes, which is very convenient. Because of the design, skin contact is negligible, so you won't get very irritated on a hot, sweaty day. However, if one of the fans gets even a single strand of hair, it stops working. It's huge! Both fans died within a week of use. So not recommended for people with long hair! I would have given 5 stars but because they are so fragile I gave 4 instead.
