Query: Biggest piece of crap in history

This is without a doubt one of the most despicable items I've ever purchased in my entire life. Stay far far away if you know what's good for you. I would sooner fan my laptop with a piece of folded up paper than waste $10 on this flimsy, poorly designed, poorly cooling, noisy fan if I were you.
