Product review (5 stars): Great function, just ok build quality
I'm an energy auditor, so I routinely see dryers lighting up cold on my infrared camera from cold air leaking inside. This is by far the best design I've seen for stopping air leaks. BUT I do have to say the build quality is not amazing, it feels a bit chintzy, it's a crummy mold. My business partner has older models on his house, and they feel much more substantial. Still, because of how well they function, I'm giving it 5 stars.
