Product review (4 stars): Great item for small spaces but difficult to attach
It was a little awkward trying to keep both ends tightened.  I was working in a very small space and after I cut both ends to fit the angle I needed, I had to "pretzel" my arm to tighten the straps on the exhaust pipe ends.  I'm not sure they stayed in place but I shoved my dryer as close to the wall as I could and there appears to be no lint leakage.
