Product review (2 stars): It works! NOT GREAT QUALITY
I recently ordered and installed the Heartland 21000 dryer vent. The vent arrived quickly and was packaged adequately. After examining the the vent I decided I needed to do a couple of things to ensure proper functionality and longevity. One thing to note is that this vent feels cheaply made. I noticed some separation on a seam where the base and vent join together. I remedied this with some plastic specific glue.

1) The internal float cup had rough edges allowing for air infiltration between the cup and the base. I sanded the bottom edge of the cup to ensure proper seating.
2) I painted the unit as suggested by the manufacturer to avoid sun damage.

Installation was simple enough and self explanatory. If there is any confusion the included instructions will guide you through the process.

I give it 2 stars due to having to put in some time finishing the product myself, overall quality of material, and price. For the money I would have expected better material and a finished product.
