### ⭐⭐⭐⭐⭐ Vent
*by J***M on 29 December 2025*

Fitted a couple of months ago and so far it’s doing the job so happy to give it a thumbs up for the price , good product.👍

### ⭐⭐⭐⭐ Good vent, but needed a tweak to stop the flapping noise
*by S***9 on 8 April 2025*

Decent quality vent, fits well and does the job. Looks neat once installed and allows good airflow. Only issue was the flap – it tends to bang about in the wind, which got a bit annoying, especially at night. I added some small foam pads either side of the flap to soften the impact, and that’s sorted it right out. Overall, a good bit of kit, just needed a little DIY touch to make it perfect.
