VIVOSUN 25 Feet 6 Inch Non-Insulated Flex Air Aluminum Duct for Ventilation Ducting w/ 2pcs 6 Inch Stainless Steel Clamps

Exactly as advertised.

I am using the 6" ducting with my 6" inline fan. Part of the ducting is venting outside, so I'm hoping it will hold up in all kinds of weather. I put a square of window screening material on the open end that is on the outside to keep bugs from getting into the duct. I didn't notice any smells, which is a plus.

Perfect tight fit, does the job, reasonable price

It works well. Durability is very good. Been using it for years now.

I was expecting the aluminum lining to be fragile - Not the case! You need some force to cut it. The best thing is recoil, Use what you need, cut and store the rest.
