My office is HOT, I mean the fiery depths of hell, pretty hot. I needed a fan that would fit my cramped desk but let some air out. I liked the pink one, it's very cute and almost big enough to blow on my face. The downside: it NEVER worked without a network connection. Right out of the box I charged it as directed and nada. Ok no big deal, I'll just leave it plugged into my spare laptop. It worked for a while, and then it stopped, only mid-spin it stopped. Mmm, no, Bueno, you're very hot, like Satan's anus here. I'm always on the move. So whenever I have a good chance to sit at my desk for a minute, I like to lift my face shield, put on my mask and bask in the cool breeze. If it worked for you, great, looks like I got a lemon. Good luck to all. I hope I survive this godforsaken hell this summer in SE TX. Wish me luck.
