Review on Hands-Free Bladeless Necklace Fan: Rechargeable Portable Neck Fan - Stay Cool Anywhere with Hanging Neck Fans, Headphone Design Wearable Fan, 3-Level Air Flow - Outdoor/Indoor Cooling (Pink) by Matt Travers

This is a good product with very light weight and good airflow. However, this product is more for relaxation. I wouldn't recommend using it if you're working in the sun or doing anything that requires airflow. The highest setting won't work as well if you're looking for heavy flow. This is a night for office use but not outdoors.
