Hon&Guan 3" x 8FT Insulated Duct with Aluminum Foil, Flexible Dryer Vent Hose for HVAC Ventilation and Duct Fan Systems, 2 Clamps Include

It's pretty stinky but I knew that going in, just let it air out for a while and it's fine. Works fantastic for my use case, venting a hot rack and a 3d printer. Seems to hold up okay, but it is pretty well protected where it is installed. It seals up well and the size is correct for my fittings.

Disclaimer: I am not using this product as it is designed.I purchased the dryer vent hose for a stage lighting project involving controlled fog placement. The aesthetics (appearance) fit the requirement, as I needed a non-reflective and darker flexible conduit for the application. The connections appear durable. In addition, I will be using the 4" diameter for attachment to fog machines and similar. However, the fit appears snug for this application. I did not confirm the length, but this is secondary to the requirement.

Longer than average vent hose. It was exactly what we needed because the installation crew only had the regular 8' hose. We ordered this hose, received it next day and did laundry same day. Perfect fit for places where the normal hose isn't long enough

xTool has a 3 inch hose, so if you buy another 3 inch hose, you would expect them to be at least the same size and work with the same couplers. But when you try to use this hose with an xTool coupler, it’s several millimeters smaller in diameter, so it definitely won’t form anything close to a seal.The hose itself is fine and feels pretty durable. It is a thick plastic, but not rigid like the xTool plastic where you can actually turn the hose in a particular direction and it will support itself. I did find that the difference in diameter between the xTool hose and this hose is sufficient enough that you can wind this hose inside of the xTool. So if you can find a coupler that works with this hose and an xTool port, this might be a good solution.UPDATE: I added two more pictures. Because it slides inside the other tube, I cut the xTool tubing to make two ends that go into the coupler and still have enough of the rigid xTool tube to provide some control and structure. I think this will work if you just use this tube to extend your existing tube in the middle. In the pictures you can see that I removed a middle section of the xTool tubing and replaced it with this. For additional structure, you could add more elbows of the xTool tube at strategic locations around this tubing.

Awesome dryer vent. Great material will last and not tear. I recommend this product if you have a dryer vent you want to hook up and walk away. Recommend. Great quality and fit.

Very flexible and can be stored in a small space. Not much insulation but seems air-tight and can be wrapped. Worked great for pushing cold air into a roof top tent. Will work for hot or cold.

Just received my hose and the jury is still out. They weigh heavier than the full aluminum hoses you get from a home improvement store. The outer coating though is much thinner than I was expecting. The product picture makes it look thicker, but in reality, it's paper thin. The inner foil is also paper thin. In saying that though, the outer layer was difficult to tear a little piece off the end as a test. It stretched, but never tore off. The hose also folds up as nice as it came. The hose clamps are a nice touch, but I would prefer wingnuts at the end instead of the worm screw. Also, as a warning, be careful when taking the plastic wrap off. My thumb went through it and got sliced on the wire sticking out. You may want to put a piece of tape or something on the wire so it doesn't happen while camping.Now the part I'm not a huge fan of and the 3 star review rating. Mine smell. Some reviewers say they don't, while others say they do. My plan is to use it with a diesel heater and figured the foil would be enough of a barrier to let any harmful smells through it. While I haven't used it with the diesel heater, I stretched them out in a bedroom and just have them airing out. I would say it filled the entire room with that plastic smell. Hopefully they'll air out enough to make the smell go away in a few days.So overall, they seem somewhat durable, they fold back up nice, and the hose clamps are a nice feature. The smell though is a bit off putting but we'll see if it clears up.

I read a couple reviews before I bought this talking about how difficult it was to actually put over a vent, but I bought it anyways. After struggling with the same issue for a minute, I figured out that you need to peel some of the black plastic away from the inner foil, just like 2 inches from the end. Once you do, it's 10 times easier to attached the end and it works perfectly for our dryer vent. Also, the black plastic makes the entire length way stronger than the standard just foil ones that you buy in the store.
