 It's great. You don't have to get an electrician up there. Nothing. You just take this fan. It's got a solar power on or solar power. Yeah. We'll take system on it. You place it on the roof. And as soon as the sun comes out, starts working, draws all that hot air out of your attic. It acts as an exhaust vent pulling up the air through the intake vents. Very efficient. And it runs whenever it wants and you never have to touch it.
