I’m not even kidding, this is the BEST handheld fan I’ve ever owned. I might be an expert on this. My classroom reaches 90 degrees and I spend hours sitting in stadiums as a sports mom. You add water to the top of the fan and it serves as a mister too. I’m so impressed with how cold it gets and how long the charge lasts! sportsmom teacherlife fan LTKmomlife LTKSeasonal LTKActive
