Product review (5 stars): dryer vent
After living with the standard Lowes/Home Depot dryer vent where the plastic disintegrated due to sun exposure and the damper stopped closing less than a year after installation which caused my laundry room to be hot in the summer and freezing in the winter, I ordered the Heartland model.  I couldn't be more impressed by the construction and design.  The plastic is thick and has no disconcerting flex in it, it will be easy to clean, and it perfectly seals out the exterior air when not in use.  The instructions suggest painting it to protect the plastic from UV rays-I chose to use plastic spray paint before installation which did a great job.  Huge improvement over the crap you can buy in the local home center!!!
