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.

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.

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.

Great quality long flexible and easy to install

Avoid!Bought to extend the exhaust reach on our portable A/C system.Length was fine, quality felt okay.However, within minutes of switching on our A/C unit the room was filled with an awful hot plastic/chemical smell which made us feel sick and the room actually started feeling warmer, it didn’t insulate the hot air at all.Sending it back as it isn’t fit for purpose, absolutely would not trust it overnight.

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

Good size of length. I am using for a.c. exhaust. Easily fitted to my portable a.c. exhaust outlet. Perfect fit and good performance.
