Hon&Guan 4 Inch Aluminium PVC Ventilation Air Ducting Flexible Hose 100mm with 2pcs Clamps for Universal Tumble Dryer, Cooker Hood, Extractor Fan(100mm*5m, Black)

Needed to replace our current one proper to a new cooker hood going in. It was a tight fit through the hole in the wall but survived a lot of shoving and pulling and does the job well.It was very flexible - having to go through a a wall and around a bend.

Appears good quality but only time will tell.

As expected, not much to say about it, length and diameter are correct, decent enough quality, wire structure is strong enough to hold its shape and the main pipe material isn’t flimsy

Great product. Colour brilliant

Disappointed with Insulation and Build QualityI bought this exhaust pipe because I needed a longer one to reach my window, and it was advertised as insulated. Unfortunately, the insulation is not effective — instead of cooling the room, it’s actually heating it up due to excess heat radiating from the pipe. The outer surface gets quite hot, which defeats the purpose of using an AC.Additionally, the outer layer feels cheap and flimsy. It doesn’t seem like it will last long with regular use. Overall, I'm very disappointed with both the insulation performance and the build quality.

Excellent product. Flexible enough for what I needed it for. Although other reviews say it is flimsy, I found that flimsiness to be what I needed to be able to easily go through a few bends. I found it to be of good quality and didn't break or get damaged when pulled through a few holes. If you need a duct that is firm and rigid and keeps its shape, then this is not what you're looking for.

You will definitely need the included clamps as it goes around my ac exhaust. But good product either way

Bought as an extension for a portable A/C outlet. Length is perfect and it is very flexible. It is reasonably insulated and does the job well. It folds down quite small for storage.The only downside I have found is that the spiral is left handed an my A/C outlet is right handed, but I managed to stretch it over the end and it has stayed on.
