YIJUHOU 4 Inch 8FT Dryer Vent Hose, Aluminum Foil Ducting, Silver Flexible Air Duct with 2 Clamps

It is very heavy duty. Much heavier than the one I bought locally. The foil tears quite easily. The coil wires make bending it difficult but it holds itself at the angle you bend. The local purchase just flops and needs much more support. I am using this as a vent tube for a laser cutter so it is good that it holds its shape.

Cheaper than Wal-Mart love it

Item is made well but TOO SMALL. Size of 4" is being done too literally in this circumstance. Its supposed to be for 4" ducts which means it needs to be a tiny bit bigger (maybe 4.2"). It won't fit on my duct pipes (and yes I'm aware how they do fit on snuggly). I went to lowes after returning this purchase and got another 4" and it fit right and snuggly. Maybe if your connection pipes are smaller then it will work but this was smaller than the 4" labeled hoses I saw at store.

Works well as long as it doesn't get crumpled behind the dryer

Simple, quick, and easy to install
