I have 2-733's in my condo on the floor pointing to the ceiling. In the summer the a/c recirculates floor to ceiling. When the heat is on the fan circulates the floor's cooler air with the warm air at the top of the room (feet stay warmer). My family still has 2 large vornado floor fans from 1954 - THEY STILL ARE STILL WORKING. I carry my other vornado (5 speed) to our condo's workout room where it amazes people by projecting a "column" of air across the room 50-65 ft away. Needless to say I am a staunch Vornado "fan" (no pun intended). Today I ordered a Vornado Flippi 8 personal fan and an iControl Whole Room Heater. In the October 2010 Consumers Reports in the "Forced Fan Convection" Category a Vornado came in #1. And there's no fooling arond with CR's testing and results.
