Product review (2 stars): Doesn't fit a standard dryer duct
Like several of the other reviews, I agree with the fit comments after receiving the product.  The portion that attaches to the in-wall duct and then to the wall is the same size as the duct.  This doesn't allow the product to mount over or inside the existing  in-wall duct; defeating the purpose of having it attach to the wall.  Great idea, but a flawed product that needs some redesign.
