I had a 9 y/o Damon Challenger.
While driving down the highway the wind broke and blew the lid off. I went to Fantastic Fans web site to see if I could order a new one but there was nowhere to purchase one. I noticed that their website said the the lid had a lifetime warranty. Since I was not the original purchaser I figured that it wasn't covered. I sent an email to the company to find out where I could buy a replacement. To my surprise, they responded back saying that it was covered under warranty and just needed to know my mailing address and the color of the lid.
The tech also said to make sure that the vent is all the way open when traveling. He also said that it may have bent the crank arm so they were sending me a new crank assembly along with the new lid. All of this was at no charge. There wasn't even any shipping charge. Once I sent the info that they needed, I had the new parts within 3 or 4 days.
They stand behind their products and they made the whole process very easy.
