No one enjoys working in a stuffy office with no windows on a hot summer's day. When the temperature reaches anything above 20 it becomes a bit unbearable. This super cool clock is here to wipe that sweat off your brow (not literally, but it could prevent this ever happening). Plug the LED Clock Fan into any USB (Universal Serial Bus) port & it will power the fan to send a cool breeze your way. As the fan blades are spinning, the cleverly aligned red & green LED's clearly display the time on a standard analog clock face, with moving hour, minute & second hands. The soft fan blades provide super safe use, even if you accidentally fall into the spinning blades fingers first, it won't hurt but it will create an interesting noise!
