Cool in every way possible; this fantastic gadget is here to make summer more enjoyable! With a USB cable, it does not require any external power sources, and provides a steady blast of much-needed cool air. Position your fan virtually anywhere on your desk or table, and be the envy of all your colleagues, as they suffer the most humid afternoons! Just plug it in to your computer/laptop, switch it to "On", and enjoy a quiet breeze, all day long (we actually have them on our desks, here at Home Bargains HQ, and don't know how we ever lived without them!).
