Rated 5 out of 5 by Easy Installation, & Works In The 'Frig... LOL I got 2 Turbine Boss', put them in the frig, they closed & I let them warm up, they opened as advertized. I have 16" turbines so I plugged the gap with insulation. I've checked them in the morning & they're closed, checked them later & they opened all the way. So that saves me from bagging & un-bagging the turbines, good to go. October 24, 2012

Rated 5 out of 5 by Chicken coops Works good for chicken coop ventilation . Put two on side and one in top with the wind turbine. No drafts. Plus I don't have to worry if I forgot to close them in the winter. October 18, 2014
Rated 5 out of 5 by Damper These things really work! Put it in a separate garage, open in warm, closed when cold. Keeps garage about 5-8 degrees warmer in cold weather, silent operation. March 18, 2014
Rated 5 out of 5 by Easy enough for the DIYer I have a 1930's 2 story home with a steep roof which makes it very difficult as a senior to cover every winter, which I strongly believe in doing. No I don't have even think about it anymore. As suggested with the instructions I tested the unit first in my refrigerator and it worked everytime. May 28, 2014
