Product review (4 stars): Tough installation
It would be hard for me to put into words how difficult it was to install this behind my dryer. My vents did not line up vertically like the pictures in the instructions show. I felt this made it exceptionally more difficult to install. I consider myself pretty handy, although I am 7 months pregnant and this is a small space to be working in under such conditions. However, I can't fault the product for difficult installation. It still appears to operate as it should and seems much safer than a crushed tube behind the dryer.
