I live in a 2 year old property that had the ‘flap’ vent grille style fitted. These were very noisy, flapping around when there was any wind, and one of the flaps eventually broke (as per the picture), so not great after only 2 years.So I wanted a replacement that a) was not noisy and b) would last, and these grilles looked to fit the bill. Quality is good, I liked the dark brown colour, matched the brick colour nicely and they were easy to fit (I fitted 2).With the new grille you first need to remove the louvred part, which is simply done by getting a small flat headed screwdriver and prising away from the frame of the grille. Some care is needed, so not to break the holding tabs, but took less than 60 seconds.Once I removed the old grille from the wall I found that the 2 screw holes matched the new grille, so was a case of snipping off the cable tie that held the pipe to the grille, attaching to the new grille, wrapping a new cable tie around and screwing the frame into the wall. Place the fly screen and then the grille into the frame, again being careful and job done! Note… as you are installing ensure that both the frame and louvred grille are placed the right way up.It was very windy last night and it was whisper quiet (great!), so works very well. Time will tell on longevity but they look the part and are solid….recommended.

Does the job, lets air flow through inner mesh and no flapping noise when windy

Excellent product

Fantastically easy to fit, just a matter of easing the broken one out, sticking NO NAILS adhesive on the back of the new unit and pushing it into the vent pipe! Job done, the noisy old flap vent and my wife are both silenced now, well worth the money, the silence is golden now, even on a windy day or night it's like a whisper now, compared to the irritatinglyloud noise against our neighbour's partition wall! WELL HAPPY!

Poor design.The lugs fastening the frame to the grill are pathetic and brittle.1. Get the cover the right way up (you work it out - no instructions)2. Ensure you know which way round the cover goes in the frame ( no markings)3. If you get that right, and the lugs don't snap off, well done.

A good replacement.

What’s not to like? You get what you buy, it’s simple, the insect mesh is very effective and it’s easily mounted if you know how to drill masonry/brick. Would benefit from being slightly longer to insert into cavity but that dependsOn your specific needs. It worked for me
