Rated 5 out of 5 by from Better than the 3 flap style I replaced old flap type vents with these, after 1 of the 3 flaps inevitably breaks and falls out leaving an unpleasant sight and rain gets in. These are a much better design, albeit that said when placed on walls below that of knee level, I've had a customer ask for a new one as they had broken the one I'd fitted when pushing a lawnmower past. Great value for money.

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.
