We have used fans from many, many other manufacturers and none compare. The Vortex technology really works! We have four of these fans that we use on a regular basis and they just keep working and working. They are easy to maintain (oiling the motor) and are well-built. These will be my first choice for a long time. I am a little concerned that their "consumer-grade" fans are becoming more made out of plastic rather than metal like this one is. Please don't make the wrong decision to get "cheap" Vornado!!
