### ⭐⭐⭐⭐⭐ Brilliant fit
*by A***R on 27 October 2025*

Quality products fitted perfectly reducing 6” kitchen extractor to 5” vent pipe. Price and delivery very good what’s not to like and why it’s not rated higher is beyond me .

### ⭐⭐⭐⭐ Does not fit a 100mm outer pipe but good quality
*by A***R on 30 June 2024*

Crazy I know but I had a tumble dryer with an outlet of 100 mm and the smaller dryer needed to be 80mm so I ordered this to do the job trouble is it fitted the 80mm new dryer but obviously the 100 mm outer duct was 100mm so it didn’t fit we had to get a piece of plastic bigger and tape it up! My fault but it was good quality plastic
