    Passable for Fixed Installation
    Your review:
    OK for a very fixed installation inside. It is NOT suitable for for anything that requires the ducts to survive sunlight or movement. Sun will destroy this product.
    Cheap compared to robust HVAC ducts that can be used in multiple locations. NOTE: slanted review by Global as lowest rating is FAIR. Really? The worst product possible is fair?
    Sunlight will destroy this product leaving only a skeleton of wire. NOT good for outdoor use. NOT good for over a short time. Ducts were not good for outdoor use on 3 locations before they deteriorated. Indoor and fixed locations only.

    pretty good!
    Your review:
    I needed duct to run the air from my whole house fan outside. It was quite a project for a 70 year old woman. And it took me a couple of days to do it. I like the quality of the product. It was important that it could be used with a lot of heat and with my 4700 air flow. Very happy I found something. Thanks
    Hard to find a size that would fit my 18 1/2" diameter fan and the material I needed.
    I was being careful but the wire started unraveling fairly easily. Could be my lack of experience.

    HVAC Duct 20 inch
    Your review:
    Excellent product and great price. I used it to hook up a ventilation system for my paint booth. Exactly what I needed via Global Industrial as I couldn't get the same product locally or at the best price.

    Happy Overall.
    Your review:
    I felt the price was slightly high and I would like to see a discount for buying in bulk, but overall I am impressed and would certainly order again. Thank you for making my order experience positive.
