Review on 🌀 Stay Cool Anywhere: Rechargeable Portable Neck Fan for Hands-Free Cooling - White by Ryan Gillett

They create a pleasant breeze in warm weather. They are adjustable and the "arms" bend so you can point them where you want. There are three speeds, which is nice. I was afraid my hair would get tangled in it, but so far it hasn't been a problem. Air exits through the top vents (which took me an obscene amount of time to figure out!). They charge quickly and can be used while charging if desired. They're pretty loud, which can be good if your house is full of people and you want to drown them out for a while.
