After 2 years of running 24/7, my Vornado started making a whining noise. Called customer service and the problem was quickly resolved with a replacement. Excellent customer service. With the purchase of my Vornado, I was able to go from 3 fans running in my home down to the one fan. It works great. Initially, I was a bit skeptical about spending that much on a single fan, but overall, it was the right choice. In the 2 years that I had it, I would have easily gone through 5-6 of the other brands. The energy savings alone of not having to run 3 fans continually paid for my Vornado. This is the only fan for me from here on out. I would wholeheartedly recommend it to anyone. GREAT WORK VORNADO!!!
