Product review (5 stars): A fair price for a good product.
UL-listed, much better than the previous shredded old fire hazard that the previous tenant or landlord had put there before. Does the job at a nice price. Much better than those old paper ducts. Not quite as sturdy as the hard aluminum ducts, but the flexibility of this hose in a tight spot is not to be denied. I found that the included attachment rings worked fine for my needs, but may depend on your specific dryer model.
