This kept me cool at the 18th Anime Expo convention where the whole weekend was at 90s peak and let me just say. Everyone in the queue was jealous of me lol my friends liked it as much as I did - make sure to use it sparingly at the highest setting as it's a big battery drain. Using the lowest for the longest time and the highest at times is the way to go! :-) Overall it's a really great fan for the price and size and it charges with my USB battery!
