I have owned many Fan-Tastic Fans in my RV's and generally they are an excellent product, if pricey. It was with this expectation that I bought this fan. Well, I guess everything a company makes can't be a home run. This fan is a full 6 dB over my $21.99 Wal-Mart fan and an irritating noise to boot. When you charge $80.00 bucks, only $40.00 less than you can buy an window a/c from home depot, you expect an outstanding product. This is not an outstanding product. Yes, it's 12V, which I guess adds a dollar of two to the cost of a fan motor, but come on, this is not good for your reputation. $29.99 maybe....It's coming back for sure...
