## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by S***7 on 22 November 2025*

Used to connect the ventilation hose in my sailing boat to the inlet blower onboard. Excellent fit. Highly recommend it. Great value for money.

### ⭐⭐⭐⭐⭐ Good
*by D***E on 10 November 2025*

Sealed the vent, plenty of screws and bands

### ⭐⭐⭐⭐⭐ Most useful for use with Portable Air Conditioners!
*by B***I on 17 July 2025*

I had two issues once it came to connecting my portable AC’s Exhaust Duct to a window with Louvered Air Vent (1) Extending the Exhaust Duct by connecting it to another of similar diameter. (2) Connecting the extension to an Air Vent with an inlet of similar diameter. I tried numerous contraptions and wasted many hours, before I came to this one. And this has been a true life saver. It does both jobs amazingly well. Quality is second to none; as it appears to be robust and esthetically pleasing! Ordering another as a spare and highly recommended!
