Great product at a great price!
Great flexible duct at a great price point - a lot cheaper than the local hardware stores for the exact same thing. Fitment over my 4" soffit vent it pretty tight, but it can be done. Insulation seems like decent quality. The interior duct itself seems durable too (I pulled it pretty hard to "stretch" it over the 4" soffit duct and it went without ripping. Also came with 2 hose clamps which is just a nice addition (one less thing to worry about). Now it comes vacuum packed and kind of coiled up. Once you open up the plastic it stretches out nicely (kind of like those memory foam mattresses). Easy to get to the shape that you want. The entirety of the duct was wrapped with insulation as well - so it doesn't appear to be "cheap". Use - I'm personally using this for my bathroom exhaust vents. Running from the exhaust vent to the soffit vent with this line. Overall - it's great that this is available on Amazon - no dealing with the store, parking, ghetto people, paying higher prices at the store etc.

Itโs DuctingโAnd It Does Exactly What Ducting Should
Not much to say here: itโs 6" insulated flexible ducting, and it did the job perfectly. Easy to work with, solid insulation, and exactly what I needed for my project. Sometimes you just need something that works without any dramaโand this delivered. Five stars!

Tough Enough if you're careful
The inner "foil" layer was much tougher than another reviewer said. It's more of a "mylar" plastic silver mirror kind of material. I only needed 15 to 17 feet, so I didn't mind ruining the end I attached to a rope for pulling through the hordes of black widows and rattlers. The insulation is as expected. I did tear the outer layer just a tiny bit pulling it with a rope I'd fish-taped through a confined crawlspace trench I had to hand-excavate. Attaching it firmly to the flanges worked well however the Hose Clamp, or Radiator Clamp style items supplied were some metric size I had no socket bit for. So, picture a guy on his back in dirt with spider webs hanging down trying to use a flathead driver on his drill to tighten a long long long clamp. One spider said: Hey, how-ya-doin?" I have patience. I attached it to one flange from inside the home, the other from underneath. Both ends were easier than expected. This is a quality product, but fragile as you might imagine. Be careful of it and it's tough enough and a good value.

let's see!
not quite 25ft, more like 23.5ft. Used these for two bathroom vents Wish the insulation was more robust, it's pretty thin. let's see if it'll work. the gloves in the picture is not what's in the box, the video claims they are cut resistant, but what arrives in the box are cheap cotton gloves.

Ok and it worked, but thinner material.
Needed to extend a register in the basement and this worked for the purpose. Much cheaper than alternatives, but the material is a little think and tears easier than a name brand product. Worked for my purpose, but just be careful when slipping over the fitting.

Durable material
Works as expected. Doesnโt tear easy during installation. Exactly what I needed to install an insulated duct through my unconditioned attic space.

Junk; don't waste your time!
This product was very disappointing for two reasons. First, the inner aluminum foil duct was so thin and flimsy that it was impossible to get it onto the vent structure without tearing. I finally just wrapped aluminum tape around it to stiffen and reinforce it, and that worked marginally. Second, the duct clamps were not nearly long enough to wrap around the inner duct. They couldn't even wrap fully around the vent structure which is smaller than the duct! I had to use some other short clamps to attach to these to make them long enough to work. If I had not already cut the section of duct that I needed, I would have returned the whole mess. Don't waste your time on this junk!

Great duct, absorbed 95% fan noise and thermal proof
Great product with very reasonable price. Very easy to install on my new ventilation ducting to bring fresh air onto my bedroom, almost noise from the ducting fan disappeared since replacing this fibre wood one. So quiet I donโt even know the fan is on. Highly recommended

Great
Works great, easy to cut and install and keeps the steam warm enough to properly exit the loft.
