Product review (1 stars): By far the cheapest plastic junk available for your dryer.
The plastic molding has so many mold flashing that the lid would not close.
I spent 30 minutes with a utility knife removing flashing so the lid would close.
I could not get the duct to clamp onto the container, more mold flashing?
Get some used pantie hose to use as a lint trap.
The 4" X 5 foot vent duct comes much closer to 3 ft long, It does not reach to the top of the dryer.
