It works
Good product but hard to cut. The yellow insulation is very brittle and itchy.

Good quality
12 inch size. Just as good as any a/c hose I have ever used and priced well. Fit on the connectors easily. Don't judge my temporary installation, just keeping things cool during a remodel. If you roll a couple inches of the foil sheath back under as pictured it hides and contains the fiberglass that is very dusty and itchy.

Tight fit
I would guess it is a R4 rating. It is very tight to fit a 12" duct. I managed to get it on but it took effort and I did not need tape or strap to hold it in place. The inside is a thin cheap film compared to the normal thin cheap plastic but it did not tear or puncher when I forced it on the opening. Time will tell if it was a good buy.

Cheap product, much better options out there
This is by far the cheapest duct I have seen. The insulation is cheap and itchy, the actual duct portion tears easily and is smaller diameter than it should be. Makes it nearly impossible to get it over the duct boots. I bought one at home Depot and will be returning this cheap Chinese crap.

Works but I will not use it again
Works like it supposed, Great price, unfortunately not very crazy for it it's very hard to assemble to the metal boots the aluminum breakes tears easy, The yellow insulation too dry it becomes like needle 🪡

Easy to use flexible ducting.
The Rubber-Cal "HVAC Insulated-Flex" Ducting Ventilation Duct Hose, 4-Inch by 25-Feet was so easy to use in a very tight space. This item worked so much more efficiently than the existing ducting it replace. Heat loss was much less. Seems to be a really good product.

Product quality excellent
Shipping / handling on the mark as indicated. Inner liner somewhat hard to get over 12" ductwork opening, otherwise fine to install - experience and quality overall very good.
