Rated 4.2 out of 5 by 6 reviewers.
Rated 3 out of 5 by it works works like it should easy to install what would you like me to write December 17, 2014
Rated 4 out of 5 by average,,, pricey, but worth it compared to the plastic vents September 14, 2014
Rated 5 out of 5 by Happy with purchace bought plastic cover first and it was just a disaster installing it, should've saved myself aggravation and bought this one in the first place November 12, 2013
Rated 3 out of 5 by Simple dryer vent with a flap, made from thin gauge aluminum Being made of aluminum should mean this vent will last for along time, although it's made from a very thin gauge. The flap valve doesn't open more than about 30 degrees, so you have to wonder whether it will allow an unimpeded air flow when the dryer is running. I returned it and bought a heavier plastic vent that opens more. June 17, 2014
Rated 5 out of 5 by exactly what I needed to vent my Microwave oven. It was exactly what I needed--hooked up my vent--works perfectly. Thanks May 20, 2014
