DC HOUSE 32 Watt Solar Attic Fan Solar Powered Roof Exhaust Fan Up to 3000 Sq Ft,2500 CFM Metal Shell Solar Vent Hail and Weather Resistance

Good solid made equipment for the roof and is working well.

This unit is larger and heavier than it looks, and moves a lot of air (not even close to stated CFM, but still very good).When installing be sure to tie it to the roof or chimney so it doesn't slide off and kill someone. I have 1,200 sqft attic and one unit lowers the temp by 25 degrees or more on hot, sunny days.

This fan doesn't cool. The air flow is non-existent. It was installed professionally and done correctly, but it just isn't effective--not even a little. I never write reviews. However, given the poor quality and price of this item, I wanted to warn others. I won't be able to get my money back since it has been installed and the box thrown out, but hopefully others won't make a mistake in buying this.

Huge. I struggled to take it up the ladder. Heavy and sturdy. I sat about a foot away and I could feel the heat blowing out. My roof needs repair so my house is hot. I was able to sit in a cooler room. Love this product.

Fantastic item very easy to install very solid productQuite

I believe this is one of the best build solar fan heavy metal around and fan blades also aluminum this is not chip material i replaced old power fan which they use so much power so far so good I recommend to everyone also adjustment for sun was easy and complete waterproof thanks I will purchase again

work but an instruction manual would have been nice

took about ten minutes for the install as long as you have all the tools with you,its heavy and large but works like a charm,pulled hot air out of the attic immediately and our small attic space and home had an immediate temp difference on the inside,i would venture to guess about 5 degrees but smaller spaces would probably cool down alot more,this is probably one of the better purchases i have made for the house ever.
