I can't speak for this particular brand, but I literally have a fan SO similar to this one (only the feet are slightly different and it doesn't have this particular brand/logo on it), and it's been a lifesaver this year. Since we have window stays on all the windows (for safety reasons – because of someone actually trying to break in last year while we were home), we can't fully open our windows, and even with the ranch sliders in the lounge open, many times, we don't always get a cold breeze, so with these mini fans at the computers plugged in to the usb slot, with a cold glass of water on a coaster nearby, it really is a lifesaver, and convenient when you're literally dying from the heat at your computer.
