Review on Rechargeable USB Personal Neck Fan - Hands-Free Mini LED Cooling Fan Necklace - Battery-Operated Face Fan with 3 Speeds - Quiet for Sports, Outdoor Camping, Office - Ideal for Women by Vanessa Lopez

I was hoping it would stay in place while walking, but when I was walking with friends it kept sliding from side to side. If I rotated one way or the other, I still had to readjust it to be centered. Battery life was pretty good and the backlight was decent too. Update 9/24/19: The company has contacted me to say that they have read the reviews and will work to improve the product and that they have found a solution to the tragedy. We look forward to their improved product in the future!
