Product review (1 stars): I would pay more for couplings to make it a 5-minute job like it should be
cheap and thin aluminum.  Why don't dryer hose companies use couplings at the end of the hose to make installation a 5-minute job?  I had to run to Home Depot twice to get it to fit my dryer vent to the outside.  I would pay more for couplings to make it a 5-minute job like it should be.
