Manrose Cowl Vent White 140 x 140mm is rated 4.2 out of 5 by 30.
Rated 4 out of 5 by from Neat Replaced a flap vent with this as the clatter when it was windy drove us mad. Easy to swap over & looks neat & tidy, but although much quieter, the gravity flap can still be heard. Might be because of the exposed position - upstairs bathroom vent? Not a complete cure

Rated 4 out of 5 by from Why pay more when this works?? This is a simple, uncomplicated vent. So why pay more than the Screwfix price??? Fits perfectly in the 100mm hole I made in the garage wall for venting of a tumble dryer. Remove the outer casing by unclipping, push the base into the hole, put 4 screws (not supplied) in each corner of the base to secure, then clip the outside cover back on. Mastic the outer edge to weatherproof if like me some brick work was dislodged during drilling and not totally smooth....job done. Will leave it for a week or so and then use the tumble dryer this weekend. Screwfix is the nuts! Simples.

Rated 5 out of 5 by from Good item. Bought these to replace the old extractor fan vents, which were flapping in the wind and driving the customer nuts. Uninstalled, cleaned down, new ones installed and sealed in under 5 minutes. Customer over the moon. Would definitely get these again.

Rated 4 out of 5 by from Great price on this essential. Seen these at twice the price in other stores. Good to have round or flat vent in one product.

Rated 3 out of 5 by from Good Value For the price I would say these are good. When I first got them (I've fitted two) they felt flimsy and the flap dropped out. There are also parts that are designed to snap off to use with round ducting as opposed to flat channel which I have used. These bits are fragile, however once I fitted the whole thing on the wall and it was all screwed in, it seems solid enough. Been in place now for about a week, and the weather has been horrendous including very high winds but pleased to say the vents have held up very well and not too noisy.
