The Zippi is a great little fan and innovative as most Vornado products are. It is completely silent in operation and very efficient at cooling a small area, i.e., as a personal fan. The best feature of the Zippe is the "blades," which are made of a soft, pliable cloth. If you accidentally touch a blade in motion you won't feel any resistance -- it's just cloth. You really have to test it for yourself to feel how great these blades are. I was amazed, and just for kicks, stuck my hand into the blades several times on the first setup.
