Product review (4 stars): Like it!
My old Lambro dryer vent broke (plastic finally gave up and became brittle after a decade of weathering) and the wife did not like the duct tape repair. Since the part that connects to the dryer hose was fine, just replaced the broken top piece with the new top. Fit perfectly and works just fine. If you are doing a replacement - don't forget to clean out the lint from the hose! Do it while you have easy access and avoid a fire and get greater dryer efficiency.
