It’s big, long and flexible
Used to direct cold air exhaust away from a swimming pool heat pump. Size good and quality good, no issues

No good for deisel heater
I was hoping it would be ok for my deisel heater but it wasn’t too good! It would be fine for a washer dryer!

Great option over rigid hoses
I never thought I'd actually be writing a review for a piece of hose, but I decided to make an exception for this.I recently bought an air conditioner in prep for summer. The duct hose it was supplied with is made of the traditional off-white rigid PVC pipe. Those are fine and do the job, but if you're using aircon in a place where light can be disruptive (e.g. a bedroom), they're a bad choice because they allow light to permeate along their length.Additionally, they're usually not insulated, which means a lot of the heat being exhausted is going to escape back into the room before it even gets to the end of the hose. That reduces the effectiveness of the air conditioner and results in more power usage.I bought this hose to solve both those problems, and it does it very well. I can still feel a little bit of heat on the hose when the air con is operating (currently only testing it rather than running it for serious usage, due to it being winter), but it's significantly reduced over the regular hose. Also, the insulation on the inside and the choice to use a black outer layer means that light doesn't transfer along it like the stock hose.

Not good for air-conditioning exhaust.
Depends on your use case. I purchase this to extend an air conditioner unit hose and due to its aluminum construction it heats up rapidly. This is due to the warm air being pushed along it to a window vent. Given that the hose becomes a major radiator of heat then it negates having the cooling unit in the first place. Might be suited to a heating system only. Solid enough construction though.

Parfait
J'ai mis ce tuyau pour ma VMC simple flux (au sous sol celle là). Parfait pour la bouche cuisine j'ai pu l'installer sans soucis. Je vais d'ailleurs m'en servir pour l'extraction car il m'en reste un peu. L'intérieur est doublé en aluminium. La qualité est bonne.

Stabiler Schlauch, solide verarbeitet – nur bei der Länge bin ich leicht ins Grübeln geraten
Der Schlauch macht genau das, was er soll – und zwar ziemlich zuverlässig. Verarbeitung wirkt durchweg stabil, nichts franzt aus, nichts reißt, lässt sich gut verlegen und bleibt da, wo er soll. Der Durchmesser (150 mm) passt auf Anhieb – kein Herumgewürge oder Improvisieren nötig, so wie man das sonst manchmal kennt.Was mir aber nicht ganz aus dem Kopf geht: die Sache mit der Länge. Angegeben sind 10 Meter, aber mein Bauchi Bauchi sagt mir, da fehlt eventuell ein kleines Stück. Ich hab’s nicht nachgemessen, muss ich ehrlich zugeben, aber voll ausgezogen wirkte er ein wenig kürzer, als man bei 10 Metern vielleicht erwarten würde. Kann natürlich auch einfach täuschen – oder daran liegen, dass sich das Ding nicht komplett auf Spannung ausrollt.Unterm Strich bin ich aber zufrieden. Der Schlauch erfüllt seinen Zweck, macht einen langlebigen Eindruck, und das Ganze zu einem absolut fairen Preis. Beim nächsten Mal pack ich vielleicht mal das Maßband aus – rein aus Prinzip. Aber qualitativ gibt’s wirklich nichts zu meckern.
