VIVOSUN Dryer Vent Hose, 6 inch Aluminum Foil Ducting, 8FT Long Heavy-Duty Dryer Hose Vent Kit for HVAC Ventilation, Exhaust, Duct Fan Systems, Black Flexible Air Duct w/ 2 Clamps

Very sturdy. Holds up well. Love the multiple layers. The problem is that the black PVC layer has zero stretch to it, and it is very difficult to wrap around devices (fans, termination kits, etc.) Once it's in place I feel better about it than duct I've used in the past, but it takes a lot of fighting to get in place.

well made and strong... it's a tight fit over the 6" ducting (and it should be) but after a few minutes of carefully working it around the edge of the duct and thinking it might tear trying to stretch it - it slipped on with no tearing...

This stuff literally fell apart on it's own! It's really thin and weak; incredibly easy to tear. Does not fit over a standard 6" galvanized duct opening.TLDR: it's less than worthless because now I have to run ductwork a second time

I’m absolutely in love with this black Ducting. Decided to replace the ugly silver drying ducting I had been using. The quality and feel of this ducting is 1000 times better than the Walmart dryer ducting. Also came with two Included duct clamps. Will be ordering more to replace all the dryer duct work. The black color just adds to it and the Material of the duct itself feels really good and study.

I used this for my portable a/c unit. It was easy to install and very flexible, yet sturdy too. Would recommend insolation around it to reduce the heat being emitted into the area your trying to cool.
