Review on Portable Neck Fan - Hands Free Bladeless, 4000MAh Battery Operated Wearable Personal Cooling With 3 Speeds & Turbo Motors, USB Powered Hanging Fans (White) by Anthony Daniels

I've bought a few of these types of fans and I like this one because it has a design that helps keep it from falling off of you when you lift one or both arms. What I don't like: The power button is a press and hold style button, the fan is louder than I would have liked and the fan guards come off too easy (they are not adjustable and don't move except when you take them off, it feels like they could fall off if the fan is dropped). Other than that, I will be keeping it because it produces a very good breeze.
