I've been buying vornado fans for years. I love the warranty and it's a fan that really works. It really pushes air and they last for years. I sleep with a 733 vornado when I sleep because I was in a car accident and I'm in a lot of pain which makes me run hot. So this fan keeps me cool hours on end every night and day. It pretty much runs 24 /7 and it's the only fan that will take that kind of beating and keep running for years. So ill only buy vornado fans when I need one. I run two of them round the clock because I also own a old house without ac. So it keeps us cool during the summer when it's hot outside and our house warm in the winter by pushes air around the house to heat it up with our kerosene heater or wood stove when its -7 degrees outside. So I would only recommend vorndao fans because they are the best on the market!
