It magically unfolds into a full-sized fan! Some compact fans are only capable of cooling the immediate area around a person, with their air extending only a few feet in any direction. However, despite the fact that it can take a fairly small form when the stem is pushed down, this fan is capable of blowing air across fairly large rooms. Therefore, aside from a bedroom, a bathroom, or a small office, you may want to use one in a family room at home or a boardroom at work. If you don't have air conditioning, or can't afford to run it at a high level, you may find it difficult to sleep on hot summer nights. In those cases, this fan can help you out by filling your room with cool air so you don't have to crank up an AC system or deal with waking up due to overheating.
