Great item. Did the job

I had problems reinserting the insect mesh after screwing vent to the wall because inserting the grill caused the louvre to bow a little.Apart from that it was easy to fit and was the right size.

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.

Looks great on red brick wall

The concept is great, a vent cover that keeps out insects and birds, whilst doing everything else a vent must do. I had to replace my vents, as a bird had figured out how to lift the vent flaps and had got access to the pipe, dumping a few twigs in the pipe, so I had to replace the vents before it got around to making a nest.These vents are great, but they are also awful at the same time. The front grill section has to be levered out, using a screwdriver, this snapped off one of the securing lugs. Incidentally, the lugs are at the top and the bottom for some sizes and on each side for another size...there are no instructions, so you only find this out by snapping a lug! In putting back the front grills, one of the lugs snapped off a 100mm vent, so in total, whilst fitting 4 vents, two lugs snapped off. This was not inexperience, I fitted 2 vents without an issue, the 3rd vent lost a lug whilst having the grill removed and the 4th vent lost a lug, whilst having the grill replaced.The vents look great, they fit well, they keep out birds and insects, but the little lugs present a significant weakness. If the lugs did not snap, this would be a 5 star review.

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!

Seems to be of good quality. Fits the air vent outlet perfectly. Easy to remove the parts that slot ito the ducting if required. More than happy with this so far. Thankyou.
