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.

It's plastic, which I didn't expect. One of the dampers came with some of the louvers loose, indicating nondurable construction. The instructions recommended to hold the damper in place with caulk, with no suggestion for holding the unit in place until the caulk cures. The spring boss extends beyond the rest of the circumference, which makes the unit out of round, binding up the louvers. It's too early to judge how well it will survive summer heat, assuming it will operate as advertised at all and not bind up either fully open or closed.

DEFECTIVE
I ordered two of these at midnight stating they would be delivered in 5-7 days This was on a Friday and they arrived the same day Friday I was surprised As the box says and the web it says pace in the refrigerator wait 30 minutes and they close one closed the other one closed about 90 percent there is a slider on there to adjust this but mine was set to zero after they warmed up the one that did not close opened all the way the one that closed all the way only opened up to 75 percent these are spring loaded so i manually pushed them closed the one that only open partial had a weak spring and the other had a tighter spring sounds like a great concept also to install you will need to purchase liquid nail to glue it into place which it does not tell you this on the HD website or the factory website only for 15" turbines they send you clips for the 17" turbine
