Review on Cool On The Go! Personal Clip On Fan with LED Lights - Stay Cool Anywhere, Anytime - USB Powered Fan for Ultimate Comfort - Hands-Free Fan for Strollers, Tables, Travel, and More - Blue/White by Brian Fisher

This should be worth a third of what it is sold for. It's too loud for the small amount of air it pushes. It's not just wind resistance noise, but more of a high-pitched whirring sound. Every time I try to find a 2 inch wide air pocket I feel ridiculous - much like trying to cool down with the air provided on a commercial flight. Definitely not enough. I feel sorry for the people who paid for the premium version that comes with batteries. That's just outrageous. The input voltage shows that a 7.5V charger is required, but it only comes with a 5V micro USB cable. It seems like it was designed with a lithium battery, but instead they were at AA. I guess turning on the blue LEDs is optional. not 100% sure if that is the case. It seems that the maximum belt size is just over 1 inch, which is insufficient for the weight the belt is designed to support. Either way, it's coming back.
