Product review (2 stars): Too Fragile and Inflexible
It says, "resists crushing", which may be true, but it's too fragile; it dings and dents way too easily, and as I was pulling carefully on one end to expand the hose, the fastened end tore and unraveled. Specifically in our case, our exhaust duct is closely adjacent to the mains breaker panel. Previously not a problem with vinyl duct, this aluminum duct is too inflexible to accommodate the angle and slip onto the external exhaust pipe. Ordered vinyl duct as a solution.
