Product review (3 stars): Good product but I couldn't use it. Explanation below
Good quality item, and made in the USA.

I would have kept it if I had another use for it, but when I bought it, it was listed (incorrectly) as a dryer duct, and I had bought it for that purpose.
Before I could install it, I read that dryer manufacturers don't recommend plastic ducts (including many "foil" ones that are actually made with plastic).
I contacted the duct's manufacturer to be safe and they told me, emphatically, that it is only meant for cool air, like from a bathroom vent fan.

Since I still needed a dryer duct, and wanted it to be fire-rated, I got this one.
