Product review (4 stars): Works great
Fixed our venting  problem from our gas dryer. Works well and makes all the lint and hot steam go outdoors where it needs to be. A little difficult attaching to the wall vent due to the size being the same and afraid I'd rip it trying to get it on enough to clamp it.  Took a few minutes of struggling to push and pull it down but finally got it on about an inch and  clamped it.
