Review: Ideal - Perfect and did the job
Review: Good,not perfect. - It was fairly easy to fit, you do need to get some large jubilee clips. It does work, but there are problems, when we had some strong winds the shutter went "over centre" and jammed open. I put a small screw in to stop it going too far. When the shutter is open as much as it will go, there is still some restriction to the flow of air. It is a bit noisy when the wind is gusty, opening and closing.

### ⭐⭐⭐⭐⭐ Stops the draughts
*by M***C on 10 July 2025*

Put this in our kitchen extractor fan vent to stop cold air in the coming in from outside. Read some reviews that people had found this rattling a bit when in the vent hose but haven't found these issues for us. Works well and significant drop in the cold air coming in through especially during windy and cold winter days. Worth the money for a quick DIY fix.
