This fan was... sort of acceptable? I'm a student in New York and I lived on the sixth floor of a pre-war dorm building, where it got so hot that sitting in the room was unbearable without a fan. I bought this fan to help cool down, but it honestly did little to nothing to cool my little shoebox of a room. I suppose I can't blame a $20 fan for being weak, but I will say that after only about a month of use (two weeks in the beginning of September, and two weeks in May), one of the blades just fell off. I have no idea what happened, it just dropped off as if someone had sliced it off with a knife. I unscrewed the whole casing and managed to reattach the blade with crazy glue and copious amounts of tape, but I have to say it's a pretty shoddy fan if you have to McGyver it after only a few weeks of use. I'll give it two stars because perhaps the blade thing was a fluke. All in all, it doesn't cool very effectively and it broke very quickly; perhaps invest in something a little bit more durable.
