I live in Florida and purchased this in July.  I read reviews and saw a lot of 4 and 5 rated reviews which I read on the stores site I purchased it from. Then I came on this site to register the product and found the same reviews and most of the positive reviews received some kind of incentive. So far I'm not impressed it's hot and muggy here and this vortex fan in my shop is weak. It does not push the air enough to feel the fan is making a difference in the temp. I would not recommend this fan for the price it costs and the weakness it has in moving air. I thought the principle of this fan was understandable but the application is not. On a positive note it has a 5 year warranty but I doubt 90% of the fans ever have any issues.
