Product review (1 stars): DO NOT Purchase for use as a Dryer Vent Hose!
Okay, so I don't know if this is the Seller's fault or Amazon's fault...BUT I searched using the phrase "flexible dryer vent hose" and this was one of the first items that popped up in my search results. I was looking for a shorter hose (8 feet) as opposed to 20 feet and one that was not metal. However, after receiving the duct I realized it was very plastic, and then I did some Google searches. This crinkly polyvinyl chloride duct is not meant to be used as A DRYER VENT HOSE! This material is FLAMMABLE, and really should only be used for venting cool air such as a vent system in a bathroom or a laboratory.
