This fan seemed great at first--it was quiet and powerful. After about 2 weeks of use, it started making a rattling sound on the higher speeds. After 2 years of occasional use, it stopped working altogether yesterday. Even though it is technically under warranty still, the warranty is not worth anything. To get it repaired, you have to not only pay to ship it back to Vornado, but they make you include a check for $20 for return shipping & handling. Plus, they say it will take 3-5 weeks to repair. Considering we got the fan for $31, it is not at all worth it to act on the warranty. Maybe ours was just defective...
