Product review (3 stars): Good design, but question it's longevity
This product has a great design in that it is easy to clean by removing the lid from the top if needed.  If it was constructed of a little thicker, stronger material I would give it a four star rating.  If it also included a through-the-wall length of pipe, I would give it a five star rating.  I installed it a month ago.  When the weather gets cold will it keep the heat in the house???  I will let you know.  Most other dryer vent hoods do not give you a positive seal or the ease of cleaning builtup lint that the Heartland 21000 does.
