Review on Versatile Portable Fan for Baby Stroller - Power Bank, 50H 12000mAh Mini Cooling Bed Fan with Tripod - USB Rechargeable & Battery Operated - Clip On Stroller/Car Seat/Bike (Black) by Kevin Miller

I use this fan to cool off at night when it gets hot. I wrapped it around one of my bedposts and flipped it onto the pillow. The fan stayed in place and I was happy to make room on the bedside table where my previous fan had sat. I used it at different speeds all night and it kept working. At night, it was easy to shift gears with a touch. I can't find anything wrong with the fan. I am impressed with this small powerful fan.
