HQST Solar Powered Attic Fan with Adjustable Solar Panel, IP68 Brushless DC Motor, Easy Install, Roof Mount

Easy to install, humming along on sunny days great. I've read reviews on other solar fans and seems they don't last to long. I hope this one does since its newer technology. This is my third on. I'm waiting for the next hurricane and I will let you know how it does.Had trouble with my first unit, squealing during operation. Tried the support number, but no longer in service.Search the web and found the business. Explained my concerns. With some uncertainty that they would help me, HQST came thru with a replacement unit. Very pleased with their support department.

I like the solar power, the automatic light control, no noise, and the maintainance free characteristics of this piece of equipment!
