Review on 🔋 Gazeled Battery Operated Fans, Stroller Fan Battery Operated, Portable Battery Powered Fan with Clip, 5 Inch Cordless Fan for Camping, Mini Quiet Personal Fan for Bed, Car, Includes 8 AA Batteries for Free - Enhanced for SEO by Renee Robinson

This saved my little one when we were out in the heat this summer and easily clips into her car seat when she is in the car or in the stroller. It also works really well and keeps them cool but drains their batteries pretty quickly. However, I would say that the convenience makes it definitely worth it. (Also for parents worried about their kids getting their fingers in the fan when it's secured, the holes are just the right size so they're still secure even if they try!)
