Product review (4 stars): Keeps drafts out
This is my second one of these, the other one was broken when I hit it with the lawnmower. They do a great job of keeping the drafts out of your dryer. You do need to open it up from time to time to clean it out, but not very often. Good to note that it has no pipe extending our the back like most dryer vent assemblies do. so either buy the accessory extension, or gram some extra 4" ducting to install it.
