Review on O2COOL 4 PK Portable Personal Battery-Operated Necklace Fan Set with Lanyard - Deluxe Edition by Justin Falker

This little fan saves lives. Its size makes it very practical to prevent hot flashes and the different colors available allow you to accessorize whenever you want. O bought a variety of colors. I wear one to work in a factory and I love it! It's so small and the vent directs air to my face and the straps allow me to adjust the height (how close I want the airflow to my face). Airflow rate is pretty good considering the size of the fan. Uses 2 AA batteries. I work 8 hour shifts and have to change batteries every 3-4 days. But that could be because I turn the fan off and on as needed. I am very happy with this little device. Highly recommended.
