I work in a small office with no air circulation (it is in the middle of another room, so now outside windows). I have used fans historically to keep cool, but they blow my papers all around and make work difficult - plus are very loud. This little contraption is way more effective than a fan for keeping me cool, and is much more quiet and does not blow my stuff around. I still need to keep a fan around for when I have others in my office or for actually moving the air around, but this little guy makes working in my office during the summer months WAY more tolerable. Love it!
