Product review (5 stars): it works
it works just the way they said it would
when we got the house it had a stack able washer and dryer and the vent is up high
we could not move the vent due to the way the wall was designed  so we had to come up with something else when we put in a non stackable washer and dryer  the indoor dryer vent works great for this  you still get the humidity in the air but you donl;t get the lint which helps
