Quality post!
From my own experience, I bought this fan and it broke within 10 minutes of using it (the pin fell out at the bottom and couldn't be forced back together): https://www.amazon.com/gp/product/B01AFZDND0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Looking for a really quality one that will last multiple events.

I personally use the top fan myself, if you open and close it alot one of the sticks may separate from the fan and slide around loosely inside it, but it's massive and moves a ton of air! I buy 3 packs of the bottom link and give away 10 every day. They're a little smaller and I haven't had one break, they just don't move as much air.
