## Customer Reviews

### ⭐⭐⭐⭐⭐ Ideal
*by J***S on 13 December 2025*

Perfect and did the job

### ⭐⭐⭐⭐⭐ Good tight fit
*by S***E on 26 December 2025*

Perfect for joining 2 pieces of round pipe

### ⭐⭐⭐⭐ Works fine but needed small modification to prevent it sticking open in my installation
*by H***G on 6 September 2024*

I installed this in a vertical duct above my cooker hood. I was getting cold draughts coming in during the winter and this completely solved that problem. There was one small issue in that when mounted vertically it is possible for the flap to open more than 90 deg, tip past the vertical and then stick in the open position. I added a small screw to prevent it opening more than about 85 deg and this seemed to fix that issue.
