Product review (2 stars): Best of the worst
Good ptoduct except for the fact that the plastic used gets very brittle, causing the dryer vent to crack. I haven't been able to find any better.  It is my opinion that this one, is the best of the worst.  This is my third one. They only last for 2 years if you're lucky.  When you mount it MAKE SURE YOU CAN REMOVE IT. The back side of the vent will eventually get clogged. The only way to clean it is to remove it.
